Awesome videos. Have duals without muffler on my 00 with a billet wheel from riffraffdiesel.com and a hydra chip. Often enough i find myself riding with the windows down and radio off lol
@@TheBTRGarage I got an MBRP catback on my Mustang GT, it sounds very good, I was very pleased. This exhaust sounds great on your truck, I love it! If I get a diesel truck I would get an MBRP exhaust like you did.
I've got a 99 7.3 with 4inch exhaust with a 5inch tip. The sound as it drives by, is bone shattering some times. You definitely notice it a bit more with the windows down
MBRP is a awesome exaust company. I live just down the road from their manufacturing shop in Huntsville, Ontario. I put a cat-back system on my truck 5 years ago. 4 months ago a rattle started and I figured out the baffles broke and were loose in the muffler. It only took 2 emails and they sent me a new muffler under warranty. It sounds awesome on your truck. All the shots from under your truck make me very jealous, mines a 2010 but thanks to all the salt/brine we put on the roads up here the undercarriage is rusted very badly. I just had to get the bottom 1/3 of the truck repainted. Very jealous of the almost no rust on yours.
Wow that's great support! Sorry about the rust, it does suck! I'm glad we don't suffer from it here and I'm glad to have found a truck in such great condition!
Wow! I've heard its difficult to get the down pipe to fit..(I would have a "shop" install it as I'm 70, but thought it was nearly impossible). Very Nice! I subscribed.
It can be done! Not terribly difficult to be honest. The hardest part is just getting your hands/tools back in the engine bay, where it bolts to the turbine. That part was very awkward and why I didn't have any video.
@@TheBTRGarage Good to know. I worked on sections of 2.5 million dollar "Lithographic Printing Presses" for 7 years..including in China, Phillipines, Japan (11 trips), and Australia..so I have some mechanical ability..but we get lazy with age. Chuckle.
My install did not go nearly as smooth as yours haha. I have a CCLB dually so I was having a hard time adjusting everything so it would it all reach where I wanted it hah. I got the straight pipe so mine was a little bit louder than I was expecting it to be. Thanks for the video though!! You've really helped me a lot with all my upgrades!
I'd agree, sounds very similar to the stock exhaust. I'm going to do the muffler delete on mine this week and hoping it'll just let it breathe better and not be obnoxiously loud.
I just installed this exhaust on my 2000 Ford F-250 SD 7.3L Powerstroke. This video made it very simple. Getting the stock system out wasn’t bad. The bolt on the V-band was a booger to get off and some threads were jacked up but tap and die fixed that. Installation was pretty simple-ish. The joints were still a little loose even after torqued down (any suggestions???). Also, I added a black tip for aesthetics, but it seemed pretty heavy for the length, so I cut the pipe a couple inches so it wouldn’t stick out quite so far and reduce the torque/leverage in the system. All in all, it took me about three hours start to finish. Thank you for the great video!!! It made the job less daunting.
Thanks, glad the video was helpful! Are you talking about the slip joints being loose? You can always loosen them back up, make sure they are fully engaged, and re-tighten. I wouldn't worry about it too much though, unless it is an extreme situation.
@@spoperquimix1 So it seems the mpgs have improved a little. The first thing I noticed was more response from the engine when accelerating. As for mileage, prior mpg was an average of 13-15 mpg ish. I just drove to Colorado and back from San Antonio and averaged 15-17. I’d say it made a small improvement.
Put the egt gauge in the manifold like the others say. You also want the probe in the center. And to not have wall material making the temp the probe reads be less accurate. Also, cut the pipe so that the tip actually makes a sound difference. What's the point of the tip when the pipe is near the end of it. And loose the muffler. It will sound way better!
Enjoyed the video Justin. I just purchased an 02 Ex with the 7.3 and only 185,000 on it. I’m going to start to do a few upgrades for better MPG myself and was wondering have you noticed a significant increase yet?
Thanks for this install info.... planning on doing mine today. Identical 02 7.3.... got exhaust as a christmas present to myself a couple of years ago.... time to put it on! LOL I already have a Wicked wheel 2... look forward to hearing the turbo whine better
@@TheBTRGarage idk that would be cool because its a 4" down pipe at least i thought the last time i looked . we havent ordered our yet but i did get the header rap for the down pipe . hope your day is going good
Yep, well aware of the difference in temp readings due to the location. I am going to re-install the probe into the manifold here soon and do a comparison on how much different the temps are.
Should have put the egt probe in the driver side exhaust manifold. To get real egts. I'm the down pipe your looking at a 4 hundred degree difference. So by the time your gauge reads 900 it's really at 1200
So I have fake EGT's? 😂 I've heard this from multiple people already. Even though I installed where the instructions said to install it, I will be moving it to the exhaust manifold to test it out. I don't believe there is a 400° difference but that's what I want to test and find out. BTW 900 + 400 is not 1200...
Hi great vid I noticed that you put the egt probe post turbo which is ok if you have one pre turbo or don't have a chip/tuner on the truck but if you do have one you must have one in the driver's side exhaust manifold ask me how I know 😥 I love the content and you are doing a good job with the truck keep up the good work 👍👍👍
Thanks buddy! I do not have one in the manifold at the moment but I will look into that. The gauge instructions said it would be fine an inch or two from the turbo, hence the placement. Did you burn something up in your truck? Just curious what happened so I can avoid the same result if possible 😁
@@TheBTRGarage yes I over heated the turbo not bad but it could have been real bad because you can cause the turbo seal to leak and then the motor will run away and it will not stop unless you block off air to the engine and if you can't then it won't stop until all the engine oil is gone 😬 most of the time you will melt the pistons first. But in my case the turbo was already weak so it just said no more which turned out to actually be a good thing because I heard it make a bad noise and stopped. Thanks Heath
@@TheBTRGarage the egt probe being after the turbo gives a cooler reading than before so if you are at 1200F post turbo you could be at 1400F before the turbo. Now I will say that if you don't have a tuner on the truck it is hard get the egts high enough to hurt anything because ford programmed some safeguards in the pcm thanks.
Thanks for the info, I had not heard of the run away engine scenario. Now I know what to do at least if it happens. I do take into account that my EGT gauge will read a little lower because of the probe placement, so I do pay attention to that. I have DP Tuner on the truck but the only real work the truck gets is towing my enclosed trailer. I rarely see EGT's above 800F when towing, so far.
I'm asking this question, because I've never messed with exhaust... My question is this. Is there no issues where the 4" replaces the 3" and where it clamps to the turbo, with the 1" size difference? Would I need to buy an adapter to make up for the 1" increase in size?
Thats thebperfect spot for a egt on that exhaust system. A little planning goes a long way drilling and tapping with that out of the car is the easiest best way. That pipe is thin did the threads hold up for you?
It held up fine there. But, I did end up moving the probe into one of the exhaust headers on driver side (3rd one back from the front). The temp reading on the downpipe where I had it originally is about ~200° lower.
@@TheBTRGarage I wonder if that is heat soak in the piping. You want the exhaust gas temp not manifold temp and I would think that turbo outlet is the most accurate reading of what is happening. Downstream of all of the cylinders. They move o2 sensors on turbo gas cars further downstream to prevent fowling but up by the turbo is the most accurate reading.
@theccwdad Yea, that reasoning is why I put it right after the downpipe originally. But, you might notice in the comments several people saying that's wrong and put it in the manifold/header pipe 😁 I thought I'd do it just to test, so now I know what readings are in each spot.
I wonder what a 5 inch exhaust would be like... Im thinking this for my truck.. Have you done a tuner yet? I have a Hydra tuner, they are specifically designing for the 7.3 changed my shift curves and gets me 2 mpg in faily driver 65 hp mode. You can build the tunes or they send pre loaded.
EGT gauge Should not be installed in the downpipe. It goes behind the number 8 Cylinder on the exhaust manifold itself. You will be getting false cooler readings if you install EGT probe in the downpipe. EGT probe needs to be as close to the exhaust port on the head as possible. You are at least 200° cooler in the downpipe then you are in the exhaust manifold it’s self Just saying
Right, this has been beaten to death already in the comments :) The Autometer instructions tell you to put the probe right after the turbo, IF you cannot install into the manifold. I couldn't at the time, so for now it is in the downpipe and I am aware that the temps are going to be lower. That said, I WILL be moving the EGT probe into the manifold for a more true reading in the near future here. Stay tuned for that video as well as the comparison of temps between the 2 locations!
Yup yup. Gotcha! But it’s also very simple To just lay on your back under truck and drill hole and tap exhaust manifold. I know it sucks but it would have been done right the first time. Obviously you have to do this carefully so you don’t get metal shavings in Manifold. A good dose of grease on the tap helps with that and shop vac with tiny computer cleaning attachments. Good luck man!
I looked at a few, but the MBRP was the best bang for the buck and had good reviews. I'm sure there are others, but for a turbo back exhaust this one was good (hard to find the turbo back version anymore though 😕 )
A friend of mine just picked up a nice early 2000s Superduty dually with a 7.3 for a welding rig and it has 4" exhaust with nothing but a mbrp muffler thats outside diameter is not much larger than the pipe...like the O.D. of the muffler is like 4.5"! On a 4 inch pipe it's barely noticeable. it also has a aftermarket cold air intake. And it is not loud at all, it really doesn't sound a whole lot different than a stock truck...? are the 7.3 PS engines know for not having a very loud exhaust note? I've heard really loud diesel trucks and this is not one of them, what more could you do to it to have a nice rumble other than remove a muffler that's likely not doing much muffling anyway or is that muffler way more restrictive than it looks?
Going to a 5" exhaust will make it louder, if thats what your friend is looking for. And/or straight pipe it with no muffler at all. My truck, with the 4" exhaust and S&B intake, is definitely louder than stock and I wouldn't want it any louder. On long cruising trips the engine noise can get annoying to be honest.
@@Pantera972 for real though, go 5” exhaust. Egts dropped a solid 50-75° and the sound is tons better. Downside is it gets annoying after a while at highway speeds
On the highway does this drone or is it OK? Jody at DP-Tuner that he needed to add a Corsa muffler on his Excursion to make long drives more pleasant. Also now that a year has gone by what happened to your MPG after the Tuner, intake and exhaust? One more question, did the location of the EGT work out, or should I drill into the turbo?
Sorry for the late reply, didn't see this! I'd say it doesn't drone much if at all. It is not quiet, but you just hear smooth V8 engine rumbling at highway cruising speeds. MPG did not change that much, maybe 1-2MPG while towing. What really changed was just the effort of the engine to pull loads and get up hills and inclines. With the stock stuff the truck was constantly chugging and downshifting on even the smallest of hills. Once the parts were on you could just hear and tell the engine was breathing more freely, rarely downshifting. EGT pyrometer works out fine in the spot I put it in, you just have to be aware it might be a couple hundred degrees higher than if you had it in the manifold runner (where most put it).
@@TheBTRGarage thanks for your thoughts. I installed my stuff. Higher temps than I'd like! Louder than I'd like. Much better apparent mpg but i have not calculated a tank yet. Finally it gets up and GOs!!. I like the way it shifts.
I really enjoy you're video's on the 7.3L, I use Flo-Pro exhaust system's because they use a better clamp, and the downpipe connection for the turbo flange is machined then welded. The EGT probe should be mounted in the driver side exhaust manifold for a more accurate reading, pre-turbo is under high pressure (temp) and the post turbo is low pressure so you generally get a few hundred degree's in temp change. I would really like too see you install the PHP Hydra chip over the DP tuner, the Hydra is ounce it's in you can change program's and buy custom tune's from several tuning guy's, much better chip.
Thanks for the comments! After getting some feedback from you and others, regarding the EGT probe, I am going to move it to the manifold here soon. I'll make sure to do a video for that. I may switch to the Hydra chip in the future, but right now I'm running good with the DP Tuner and I have the one that allows you to add programs to it yourself as well. Really, all I use the truck for is towing and occasional daily driving, so I do not need many options.
IMO leave the stock exhaust alone on these trucks except for maybe the muffler . These 4" slip joint exhaust systems are all kind of a pain in the butt to install and don't really do much for performance. And a lot of times they will rub and bang on stuff because of the larger piping and cause issues.
I just did the same mbrp 4” system and have the same “0” clearance issue at my rear shock. I have it set about 1/8”-1/4” away but i know it rattling against it. How has yours been? Anything you did to get it to adjust further away? I swear I’ve tried almost everything lol
So far it has been a non-issue. I know it probably rubs the shock there, but I have not been able to hear it. I'm gonna do a 2 year review here soon and I'll show what kind of wear and tear might be on the exhaust.
See so many videos were people have to cut the pipe, how did you get it out and more importantly get it in without cutting. Also I believe you have a four-inch pipe. I’d like to help you out I’m going to order your system from the manufacturer. Is there a code I can put in to help you out. My downpipe is cracked
Howdy, I recently purchased a 97' F-350 7.3l. Like you, I am looking for efficiency and MPG gain. As its almost been 4 years, how much increase in MPG have you seen? Looked like this was about a 15-18 hour job- is that correct? Great video and thanks for your time.
You won't see any MPG improvement with just the exhaust. Combined with an intake and tuner you get maybe a couple more MPG. That's been my experience. The exhaust makes the engine feel significantly less restricted and run smoother however.
@@TheBTRGarage Would you then recommend waiting on the exhaust and focusing on the intake/tuner? Is there a specific tuner you used that you like? Again, I am not looking for hp maximization or to be ripping around town. Simply interested in efficiency and MPG increase.
@@prescottwidly5006 I would do both the exhaust and intake before the tuner. The engine needs to breath more efficiently, so those 2 things are recommended. Followed by the tuner, which efficiency is maximized by the bolt-on upgrades. I have a DP Tuner now, but would go with a PHP Hydra if buying today. In fact I'll probably switch to one soon. amzn.to/3CU0928
@@TheBTRGarage Thanks for the info and sharing your experience. I’ll go ahead and order this from MBRP and get an intake as well. Next step will be the hydra tune sometime down the line.
Not from just the exhaust. All my upgrades combined, including the tuner, were probably 1-3Mpg increase when towing. It was not significantly, but the truck works much less to tow the same load, with the upgrades installed.
Depends on if you're truck came with one from the factory. If it did, yes you still need a cat'. My truck did not come with one from the factory, because its so old, so not required.
That is one sweet exhaust system. Love that throaty sound. How do you get around the lack of a catalytic converter? I have a 2000 7.3L and here in Az we have yearly smog checks. They always look under the truck for that converter.
Have you had any issues with passing an emissions test now that it's installed? I ask because I am too a front range resident looking at adding that exact exhaust system to my 02 7.3. Thanks for taking the time to put out these thorough videos! Much appreciated!!
Yep, love it! It sounds great at tow speed, which for my truck is optimal around 77mph. Not too loud but you can still hear the V8 rumble. I'll be doing a video here soon where I take a look at how the exhaust has held up to the weather and general wear and tear since I installed it.
Hey I love your videos, very thorough! I did want to know if you had went with their aluminum or stainless steel system, and how its holding up so far? Thanks man, looking forward to more vids!
That's where engine RPM's, EGT's, MPG, and gearing is optimal with my truck and engine (when in a 75mph speed limit zone). If I go 70-74mph it hunts between gears, EGT's climb, and boost fluctuates. If I go even slower, it is not optimal again until about 60mph in 3rd gear. I'm sure it's different for different trucks. As for safety, I tow where I feel confident in the truck, and this truck easily handles that load at that speed. In my old F150, I wouldn't get anywhere near that speed because the trailer overwhelms the truck.
I fished it up from underneath the truck, it did take some time and was a tight squeeze. Then had someone hold it in place from the bottom while I bolted it up. I wonder if the 99 is slightly different fitment?
I have this in my 7.3 for almost 5 years. I think it’s louder than stock, almost annoying. Going to install a resonator before the muffler or maybe inside the muffler. I want the flow not the noise
That is the ideal location. The Autometer gauge says to install where I did, you just have to be aware that the temps will be a bit lower than if in the manifold. I will be relocating it to the manifold in the near future to test the difference.
how much lower are you suspecting the temps to be from the downpipe?... i have a 2000 7.3 excursion just received my MRBP 4'' exhaust and waiting on the edge insight with the egt probe to arrive so not sure if to just drill and tap the downpipe like you did or do the manifold
How did you come up with that location to install the egt probe? 9 out of 10 online videos show it in the drivers side exhaust manifold. Is the down tube a better location or is that just the location for a 7.3 not a 6.0?
That's where the instructions tell you to install it, there or the manifold. It also talks about the difference in temps and to be aware of that if you install into the downpipe. I will be moving it to the manifold at some point, and will test the difference in temps compared to the downpipe.
Thanks again, my truck is pampered, doesn’t do much calling anymore. Just wondering if a muffler delete would help. Instead of putting a new exhaust. Plus it’s cheaper. Although a turbo muffler is basically a straight through anyways correct. Thanks for let me pick your brain. Bill
Not faster, but the truck definitely seemed less "choked" than with the stock exhaust. Felt like the engine didn't have to work as hard to do the same thing it did before (tow or whatever).
Not significant, I think I answered in more detail in a other reply. What is most noticeable is how much less the truck has to work when towing. It just moves air and makes power more easily.
Hopefully you were able to get it installed? The downpipe is definitely a tight fit, but it does work. Just have to mess around with it for a while to get the right orientation.
How so? Just because it doesn't have the muffler/resonator? I agree it is probably better straight piped, but I can't imagine it is very significant. The muffler/resonator is pretty short and not very thick.
BTR Justin don’t get me wrong it’s nice but if you got it tuned at all or plan to in the future it’s much better straight piped so the motor can breathe better. Even without a tuner you get a nice hp bump with the straight piped version. I got one on my 2000 7.3 and it’s honestly not that loud and it sounds good too.
*I'm really loving the MBRP exhaust! What do you guys think of the sound?*
It will get a bit louder once the packing in the muffler has heat cycles on it.
I have the same brand, in 5" though, with muffler. I love it, has such a deep rich tone to it.
Awesome videos. Have duals without muffler on my 00 with a billet wheel from riffraffdiesel.com and a hydra chip. Often enough i find myself riding with the windows down and radio off lol
Sounds amazing!
Your suppose to cut the end of the tail pipe off then put the tip on not have the tail pipe inside the tip
If you're going to do an egt probe, drill a hole in the exhaust manifold. If you're post turbo, you'll be off a few hundred degrees.
Sounds throaty and actually has a muscular sound. Love it.

Now I will say that if you don't have a tuner on the truck it is hard get the egts high enough to hurt anything because ford programmed some safeguards in the pcm thanks.

Thanks for the info, I had not heard of the run away engine scenario. Now I know what to do at least if it happens.
I do take into account that my EGT gauge will read a little lower because of the probe placement, so I do pay attention to that. I have DP Tuner on the truck but the only real work the truck gets is towing my enclosed trailer. I rarely see EGT's above 800F when towing, so far.

"loud and annoying" = heard and noticed
Do the 7.3s have a drone in the cab with a 4-inch exhaust like the Cummins do?
Depends on the cruising speed, but it's just loud more than anything. At least with a mostly straight pipe setup like mine.
I'm asking this question, because I've never messed with exhaust... My question is this. Is there no issues where the 4" replaces the 3" and where it clamps to the turbo, with the 1" size difference? Would I need to buy an adapter to make up for the 1" increase in size?
No issue, you don't need to buy an adapter. This exhaust has a flared flange that goes from 3" to 4" where it connects to the turbo 👍
What MBRP series did you put on?
Did you need any tuning after the air filter and exhaust install?
You don't need it but I did install a DP Tuner a month or so after the intake/exhaust. Definitely worth it to make the most of the upgrades.
Thats thebperfect spot for a egt on that exhaust system. A little planning goes a long way drilling and tapping with that out of the car is the easiest best way. That pipe is thin did the threads hold up for you?
It held up fine there. But, I did end up moving the probe into one of the exhaust headers on driver side (3rd one back from the front). The temp reading on the downpipe where I had it originally is about ~200° lower.
@@TheBTRGarage I wonder if that is heat soak in the piping. You want the exhaust gas temp not manifold temp and I would think that turbo outlet is the most accurate reading of what is happening. Downstream of all of the cylinders. They move o2 sensors on turbo gas cars further downstream to prevent fowling but up by the turbo is the most accurate reading.
@theccwdad Yea, that reasoning is why I put it right after the downpipe originally. But, you might notice in the comments several people saying that's wrong and put it in the manifold/header pipe 😁 I thought I'd do it just to test, so now I know what readings are in each spot.
I wonder what a 5 inch exhaust would be like... Im thinking this for my truck.. Have you done a tuner yet? I have a Hydra tuner, they are specifically designing for the 7.3 changed my shift curves and gets me 2 mpg in faily driver 65 hp mode. You can build the tunes or they send pre loaded.
Yes I have a DP Tuner with the tow and daily modes. Thought about trying out Hydra Tuner at some point, heard good things.
@TheBTRGarage It's been good to me and a few of my other 7 3 buddies, what I liked is the fact it was designed for the 7.3
EGT gauge Should not be installed in the downpipe. It goes behind the number 8 Cylinder on the exhaust manifold itself. You will be getting false cooler readings if you install EGT probe in the downpipe.
EGT probe needs to be as close to the exhaust port on the head as possible. You are at least 200° cooler in the downpipe then you are in the exhaust manifold it’s self
Just saying
Right, this has been beaten to death already in the comments :) The Autometer instructions tell you to put the probe right after the turbo, IF you cannot install into the manifold. I couldn't at the time, so for now it is in the downpipe and I am aware that the temps are going to be lower.
That said, I WILL be moving the EGT probe into the manifold for a more true reading in the near future here. Stay tuned for that video as well as the comparison of temps between the 2 locations!
Yup yup. Gotcha!
But it’s also very simple To just lay on your back under truck and drill hole and tap exhaust manifold.
I know it sucks but it would have been done right the first time.
Obviously you have to do this carefully so you don’t get metal shavings in Manifold.
A good dose of grease on the tap helps with that and shop vac with tiny computer cleaning attachments.
Good luck man!
Lord this truck is CLEAN!! How long have you had this rig?
Thanks I agree! I got it earlier this year (2018), check out the video when I first got it th-cam.com/video/aLcdKsXR8sQ/w-d-xo.html
I’m getting ready to buy a 4” exhaust system, I have an F350 with a 7.3. Did you consider any other systems for your truck? Thanks.
I looked at a few, but the MBRP was the best bang for the buck and had good reviews. I'm sure there are others, but for a turbo back exhaust this one was good (hard to find the turbo back version anymore though 😕 )
I need a helper 😍
Sounds badass! Great video! What music is that in video?
Thanks! It is just a random song from the free TH-cam library. I honestly don't remember the name/artist, sorry!
How did you get the downpipe out without cutting it
Took a bit of pulling and twisting to get it out of there, but was not too difficult if I remember right.
A friend of mine just picked up a nice early 2000s Superduty dually with a 7.3 for a welding rig and it has 4" exhaust with nothing but a mbrp muffler thats outside diameter is not much larger than the pipe...like the O.D. of the muffler is like 4.5"! On a 4 inch pipe it's barely noticeable. it also has a aftermarket cold air intake. And it is not loud at all, it really doesn't sound a whole lot different than a stock truck...? are the 7.3 PS engines know for not having a very loud exhaust note? I've heard really loud diesel trucks and this is not one of them, what more could you do to it to have a nice rumble other than remove a muffler that's likely not doing much muffling anyway or is that muffler way more restrictive than it looks?
Going to a 5" exhaust will make it louder, if thats what your friend is looking for. And/or straight pipe it with no muffler at all. My truck, with the 4" exhaust and S&B intake, is definitely louder than stock and I wouldn't want it any louder. On long cruising trips the engine noise can get annoying to be honest.
Looking at getting this exhaust for my 1999. Did it get louder over time? Still recommend this exhaust?
Yep still recommended and still have it on my truck. I don't think it got louder over time.
My friend has the same exhaust without the muffler
Nice, I wonder how much louder it is without the muffler on my truck...hmm.
It will sound way better, my obs is straight pipe out the side, gives an amazing turbo whistle and a good bark when romping
Have you monitored the MPG and seeing any increase / decrease?
I saw roughly a 2 mpg decrease. From flooring it more
@@user-dn6qy1ou1f 😂😂😂💯
@@user-dn6qy1ou1f sounds about right 😂😂
@@Pantera972 for real though, go 5” exhaust. Egts dropped a solid 50-75° and the sound is tons better. Downside is it gets annoying after a while at highway speeds
That’s extremely disappointing, I’m wanting to upgrade mine to a 4” exhaust and was hoping for a much louder sound
Lose the muffler and completely straight pipe, that will be louder.
On the highway does this drone or is it OK? Jody at DP-Tuner that he needed to add a Corsa muffler on his Excursion to make long drives more pleasant. Also now that a year has gone by what happened to your MPG after the Tuner, intake and exhaust? One more question, did the location of the EGT work out, or should I drill into the turbo?
Sorry for the late reply, didn't see this! I'd say it doesn't drone much if at all. It is not quiet, but you just hear smooth V8 engine rumbling at highway cruising speeds. MPG did not change that much, maybe 1-2MPG while towing. What really changed was just the effort of the engine to pull loads and get up hills and inclines. With the stock stuff the truck was constantly chugging and downshifting on even the smallest of hills. Once the parts were on you could just hear and tell the engine was breathing more freely, rarely downshifting. EGT pyrometer works out fine in the spot I put it in, you just have to be aware it might be a couple hundred degrees higher than if you had it in the manifold runner (where most put it).
@@TheBTRGarage thanks for your thoughts. I installed my stuff. Higher temps than I'd like! Louder than I'd like. Much better apparent mpg but i have not calculated a tank yet. Finally it gets up and GOs!!. I like the way it shifts.
Wish i could afford this name brand stuff 😂
These are relatively inexpensive in my experience! :)
@@TheBTRGarage yeah but not for a broke 16 year old lol
I really enjoy you're video's on the 7.3L, I use Flo-Pro exhaust system's because they use a better clamp, and the downpipe connection for the turbo flange is machined then welded. The EGT probe should be mounted in the driver side exhaust manifold for a more accurate reading, pre-turbo is under high pressure (temp) and the post turbo is low pressure so you generally get a few hundred degree's in temp change. I would really like too see you install the PHP Hydra chip over the DP tuner, the Hydra is ounce it's in you can change program's and buy custom tune's from several tuning guy's, much better chip.
Thanks for the comments! After getting some feedback from you and others, regarding the EGT probe, I am going to move it to the manifold here soon. I'll make sure to do a video for that. I may switch to the Hydra chip in the future, but right now I'm running good with the DP Tuner and I have the one that allows you to add programs to it yourself as well. Really, all I use the truck for is towing and occasional daily driving, so I do not need many options.
Did you have to remove the transmission mount in order to get the downpipe in?
My wife would never 🤣
is the “egt “ necessary
No, it is not necessary. Just a way to monitoring exhaust temperatures, but you can install the exhaust system just by itself no problem.
IMO leave the stock exhaust alone on these trucks except for maybe the muffler . These 4" slip joint exhaust systems are all kind of a pain in the butt to install and don't really do much for performance. And a lot of times they will rub and bang on stuff because of the larger piping and cause issues.
You didn’t really tell us how hard that down Pipe was
Were any modifications done like all the other videos on TH-cam
Not really. Just have to cut the joining pipes to the right length depending on your truck.
Excellent video thank you.
Thank you! Glad it was helpful.
Where did you get those hangers from?
I just did the same mbrp 4” system and have the same “0” clearance issue at my rear shock. I have it set about 1/8”-1/4” away but i know it rattling against it. How has yours been? Anything you did to get it to adjust further away? I swear I’ve tried almost everything lol
So far it has been a non-issue. I know it probably rubs the shock there, but I have not been able to hear it. I'm gonna do a 2 year review here soon and I'll show what kind of wear and tear might be on the exhaust.
@@TheBTRGarage good to hear!
Did you get a better mpg ?
See so many videos were people have to cut the pipe, how did you get it out and more importantly get it in without cutting. Also I believe you have a four-inch pipe. I’d like to help you out I’m going to order your system from the manufacturer. Is there a code I can put in to help you out. My downpipe is cracked
I say cutting, I am referring to the downpipe
Howdy,
I recently purchased a 97' F-350 7.3l. Like you, I am looking for efficiency and MPG gain. As its almost been 4 years, how much increase in MPG have you seen? Looked like this was about a 15-18 hour job- is that correct?
Great video and thanks for your time.
You won't see any MPG improvement with just the exhaust. Combined with an intake and tuner you get maybe a couple more MPG. That's been my experience. The exhaust makes the engine feel significantly less restricted and run smoother however.
@@TheBTRGarage Would you then recommend waiting on the exhaust and focusing on the intake/tuner? Is there a specific tuner you used that you like? Again, I am not looking for hp maximization or to be ripping around town. Simply interested in efficiency and MPG increase.
@@prescottwidly5006 I would do both the exhaust and intake before the tuner. The engine needs to breath more efficiently, so those 2 things are recommended. Followed by the tuner, which efficiency is maximized by the bolt-on upgrades. I have a DP Tuner now, but would go with a PHP Hydra if buying today. In fact I'll probably switch to one soon.
amzn.to/3CU0928
@@TheBTRGarage Thanks for the info and sharing your experience. I’ll go ahead and order this from MBRP and get an intake as well. Next step will be the hydra tune sometime down the line.
Did you get a miles per gallon difference
Not from just the exhaust. All my upgrades combined, including the tuner, were probably 1-3Mpg increase when towing. It was not significantly, but the truck works much less to tow the same load, with the upgrades installed.
Thanks for the reply, I enjoy your channel.
My OEM down pipe is STUCK. The only option I have is to unbolt the transmission support bracket. No thanks!
Ouch, that's a bummer!
Very good content brother. About how long did the install take?
It took about 5-6 hours if I remember right. But, that was with filming as well.
Great 👍Video
Thanks! 👍
Im about to install this same turbo back system. Do you not need a catalytic converter?
Depends on if you're truck came with one from the factory. If it did, yes you still need a cat'. My truck did not come with one from the factory, because its so old, so not required.
Ahh thanks, mine (2004 Excursion) has been removed, so I guess I'll have to find a replacement to go with the 4" MBRP
That is one sweet exhaust system. Love that throaty sound. How do you get around the lack of a catalytic converter? I have a 2000 7.3L and here in Az we have yearly smog checks. They always look under the truck for that converter.
Thanks, I am loving it! The automatic trucks do not have a cat', there is a sticker under the hood somewhere that says no cat vehicle.
@@TheBTRGarage Wow. Your state sounds like they're very diesel friendly. It is such a pain here to get that smog check every year.
My 01 auto doesn’t have a car either
Have you had any issues with passing an emissions test now that it's installed? I ask because I am too a front range resident looking at adding that exact exhaust system to my 02 7.3. Thanks for taking the time to put out these thorough videos! Much appreciated!!
Nope, I've had emissions done twice on the truck and it is in and out. Passes all tests no problem.
Do you still like it? how is it towing at 70mph
Yep, love it! It sounds great at tow speed, which for my truck is optimal around 77mph. Not too loud but you can still hear the V8 rumble. I'll be doing a video here soon where I take a look at how the exhaust has held up to the weather and general wear and tear since I installed it.
Hey I love your videos, very thorough! I did want to know if you had went with their aluminum or stainless steel system, and how its holding up so far? Thanks man, looking forward to more vids!
Thanks for watching! I have the aluminum version. So far it has been good and I will be doing a 1+ year review on it soon, to see how its held up.
@@TheBTRGarage How is 77 mph an optimal tow speed? That’s not efficient at all, and certainly not safe with a trailer load.
That's where engine RPM's, EGT's, MPG, and gearing is optimal with my truck and engine (when in a 75mph speed limit zone). If I go 70-74mph it hunts between gears, EGT's climb, and boost fluctuates. If I go even slower, it is not optimal again until about 60mph in 3rd gear. I'm sure it's different for different trucks. As for safety, I tow where I feel confident in the truck, and this truck easily handles that load at that speed. In my old F150, I wouldn't get anywhere near that speed because the trailer overwhelms the truck.
Because of the muffler it is qiueter
Does it roll coal
Nope.
Did it help mpg?
Not that I could tell. All my upgrades combined were good for maybe +1-3MPG increase depending on the driving. But nothing significant.
How did you get the down pipe in? I’ve been at it for the better part of an hour and it just won’t fit on my 99.
I fished it up from underneath the truck, it did take some time and was a tight squeeze. Then had someone hold it in place from the bottom while I bolted it up. I wonder if the 99 is slightly different fitment?
I have this in my 7.3 for almost 5 years. I think it’s louder than stock, almost annoying. Going to install a resonator before the muffler or maybe inside the muffler. I want the flow not the noise
I was just thinking about installing a resonator in mine as well. It's not terribly loud to me but could definitely be more quiet.
i thought the egr probe is to be installed in the exhaust manifold
That is the ideal location. The Autometer gauge says to install where I did, you just have to be aware that the temps will be a bit lower than if in the manifold. I will be relocating it to the manifold in the near future to test the difference.
how much lower are you suspecting the temps to be from the downpipe?... i have a 2000 7.3 excursion just received my MRBP 4'' exhaust and waiting on the edge insight with the egt probe to arrive so not sure if to just drill and tap the downpipe like you did or do the manifold
Can I borrow your helper to do mine?
How did you come up with that location to install the egt probe? 9 out of 10 online videos show it in the drivers side exhaust manifold. Is the down tube a better location or is that just the location for a 7.3 not a 6.0?
That's where the instructions tell you to install it, there or the manifold. It also talks about the difference in temps and to be aware of that if you install into the downpipe. I will be moving it to the manifold at some point, and will test the difference in temps compared to the downpipe.
@@TheBTRGarage Thanks
Did you have to cut the down pipe or firewall.
No cutting of downpipe or firewall. Only cut was the joiner pipe near the back to fit it to your bed length.
Thanks again, my truck is pampered, doesn’t do much calling anymore. Just wondering if a muffler delete would help. Instead of putting a new exhaust. Plus it’s cheaper. Although a turbo muffler is basically a straight through anyways correct. Thanks for let me pick your brain. Bill
The one that he has,is that stainless steel or alumised steel ?
It is the aluminized one. See link in description.
@@TheBTRGarage ok thx
Any clearance problems with the down pipe and cab?
No, not with the down pipe. Towards the rear the pipe is very close to the rear shock where it goes over the axle. Other than that great fitment.
Hey Justin this is kind of off the subject did you see the article in Motor Trend Magazine about the new Toyota Supra
Of course! I did a garage talk episode on the new Supra a while back actually.
@@TheBTRGarage sorry I missed that one I will go back and take a look thank you
No worries, I will probably doing more episodes on the new Supra, actually. Very excited for that car!
You think a 4 inch is big look at a 5 inch exhaust lol
Haha, I bet!
That's what I just got for my 7.3
Feel any faster?
Not faster, but the truck definitely seemed less "choked" than with the stock exhaust. Felt like the engine didn't have to work as hard to do the same thing it did before (tow or whatever).
Sounds the same because of the muffler we have one with no muffler and that mfer sounds LOUD😂
Any change in MPG’s?
Not significant, I think I answered in more detail in a other reply. What is most noticeable is how much less the truck has to work when towing. It just moves air and makes power more easily.
Whaaaat muffler, 4in, stock is 3 .5
Does anyone know if this kit will work on a 1995 7.3 powerstroke?
Cole Patterson no
You can use MBRP but it’s 3” down to a 4”back. That’s what I’ve got on my 95 PSD. It’s more difficult to install on OBS due to down pipe clearance
take your muffler off, mine sounds way better without it, have a 7.3, as well.
Wouldn't that make it louder? Truck is already pretty loud now, would be nice to make it quieter hah.
Alex Fincher your right it doesn’t sound good until you take off the muffler
Alex Fincher
Agreed!
Mufflers are for gassers!
Straight pipe sounds better
Little bit Lower EGT’s too
Alex Fincher In maine we have to have a muffler to get an inspection sticker
you got any advice, i can’t get the damn down pipe in
Hopefully you were able to get it installed? The downpipe is definitely a tight fit, but it does work. Just have to mess around with it for a while to get the right orientation.
BTR Justin yea lol just used stock down pipe and welded rest of pipe to it because it was vibrating really bad
I wish everyone Thought 4 inches were massive.....
Giggity
Open the windows
Next video! :D
When writing this comment I am at 5:05 btw: please tell me u turn it on with no exhaust
Sadly I did not 😕
$?
They are around $435. Link is in the description.
Lose the muffler Bud
MBRP 4 inch straight is much better for the truck.
How so? Just because it doesn't have the muffler/resonator? I agree it is probably better straight piped, but I can't imagine it is very significant. The muffler/resonator is pretty short and not very thick.
BTR Justin don’t get me wrong it’s nice but if you got it tuned at all or plan to in the future it’s much better straight piped so the motor can breathe better. Even without a tuner you get a nice hp bump with the straight piped version. I got one on my 2000 7.3 and it’s honestly not that loud and it sounds good too.
