Take a glimpse into 2 fully custom exhaust builds! A ZL1 Camaro gets a double X-Pipe and G37 gets an new system to replace the rusted out factory exhaust!
Was everything else stock? Also, do you think the video sounds fairly accurate compared to in person? Sounds like a lot of drone but I'm guessing it's hard to capture the real sound on video.
Couldn't say which exhaust sounds better since the video insisted on sounding like were in the club instead of a exhaust shop. Shut the music off during sound clips
Yeah, we agree. Wish you could have heard her in person! We put most of our efforts into the cars and the media / audio stuff is all new to us! We will keep working on it though. Thank you for the comment!
@@dixiefabauto9830 Getting into media and audio stuff is hard to do. If you'd like a good cheap place to start with all that, I'd recommend the GoPro Hero 6 Black. It's what I use and the video/audio quality is fairly good for what it costs you and you can get all kinds of attachments for it to post video on your cars while your driving. Something to consider. I hope to see more from you guys, the last one was pretty good.
Will adding a second x pipe to a single x pipe setup reduce any drone? Or significant volume? Or would going dual bottle resonators be a better choice?
We actually got to do this a few weeks later. We didn't really know if we would see much at all, BUT we saw an increase of 19 WHP and 30 ft lbs of TORQUE!
Well the purpose of x pipes from what I’ve researched and learned (youtube certified knowledge) is to cause exhaust temps to reach a higher temperature helping them travel through the exhaust system a lot faster! Therefore placing x pipes further apart would help keep a higher temperature throughout the exhaust a little more vs. placing them back to back. Well at least this is me trying to put 2 and 2 together. I plan on placing an xpipe on every resonator that I remove! And switch the muffler to borla ATAK!
@@afterthoughtsgarage320 We actually got to do get the before and after dyno results a few weeks later. We didn't really know if we would see much at all, BUT we saw an increase of 19 WHP and 30 ft lbs of TORQUE with no other mods!
@@dixiefabauto9830 I sincerely enjoyed this video & THANKS for posting it. Over the years, I've done countless hours of research on H-pipes & X-pipes, etc. Believe me...the closer they are to the header collectors...the better. They need to be "a bit" downstream...BUT...not too far. In the "good ol' days", we'd spray paint about 3 feet of the exhaust from the collectors back...then drive the car at highway speeds for about 30 minutes. Straight back to the shop & up on the rack. The burnt section of paint would reveal where the hot spot in the exhaust "truly is". This is the correct place for the H-pipe. Regarding X-Pipes: They need to be "near" the collectors...not too far downstream. There are 3 advantages an X-pipe has over an H-pipe: 1.) It will perfectly balance the exhaust pulses of each bank on a V-8//V-6 engine. 2.) It will increase exhaust velocity & provide extremely efficient scavenging of the exhaust gasses from the combustion chambers. 3.) It stabilizes the exhaust sound wave; which is pleasant to us "gear-heads" :-) Both 1 & 2 will allow the engine to "breathe" more freely; producing more HP & Tq. On a properly tuned engine, these increases will be realized throughout the RPM range...considering a 500+ HP engine with 3" exhaust pipes. Regarding Dual X-pipes: There are no benefits to the engine by placing a 2nd X-pipe in the exhaust system. This is true if the two X-pipes are mated or if the 2nd X-pipe is further downstream. It doesn't hurt anything...BUT...no additional horsepower & torque gains will be seen. One...properly placed...X-pipe does ALL the "work". However, the 2nd X-pipe will further "tune" the sound wave of the exhaust. For what it's worth: There is NO benefit to "dual" H-pipes. A "properly placed" H-pipe serves 1 purpose; to balance exhaust pulses of a V-8//V-6. Still, an X-pipe performs this function with MUCH GREATER efficiency. The "H" design will not improve combustion chamber scavenging or exhaust velocity. An additional H-pipe in the exhaust system serves absolutely NO purpose. NONE. Respectfully, Ben
It would be tricky on a Silverado. The Silverado is not a "true dual" exhaust. They bring each side of the engine into 1 pipe right after the upstream cats. To do this you would have to make the system true dual first but I image it would help produce a very "deep" smooth tone rather than the "clacky" noise the Silverado's usually have.
Seems like a fun experiment. From what I hear on my speakers it sounds like your microphone couldn't handle the volume level and it sounds like there would be more drone, not less. But that's probably nothing like what it was in person. I'm curious what the actual sound was like?
@@GabrielKish Yeah, sorry about that! We are new to filming in general and that was all new equipment that we had NO IDEA how to work. We are mechanics but definitely not film experts haha. We are learning and we will get better!
@@dixiefabauto9830 It's a really cool idea I've never seen done before. I hope you continue testing different cars with your double XX pipe. Any hp gain is desired but if the sound changes that dramatically, it would still be worth getting it just because most new cars sound like shit. Your future customers need to only hear the sound of the exhaust. It could be the start of a new exhaust company.
when the video strarted i was thinking to myself : it eithre sounds the same as an single x pipe or picks up a second higher pitched resonance its loud but i don think the second x pipe has any added effect
We were still figuring out audio settings when filming this and that actually really took away from what happened in this build. We have done more Camaro exhaust than we could count but this was the first time we had ever done legitimate double x-pipes. We had no idea what would happen and the customer was completely willing to gamble on it. But we were pleasantly surprised with the results, as was the customer. Here is what we noticed... It took the "sharpness" away and gave the exhaust a very "deep" note throughout the powerband. It also took the typical drone level with running no mufflers WAY down. The pitch is also very clean and well harmonized. Not sure if there is an actual performance benefit but the sound was a step above what we normally hear out of these cars! Thank you for the feed back! We do appreciate the like and comment!
It does smooth out some the exhaust sounds on stuff with double x-pipes & cut some drone back. Did this on my Silverado a year or two ago. Really liked how it sounded.

My friend put one on his e63 AMG (5.5 twin turbo) it sounded terrible and you could hear the restriction so badly. Made a kind of restricted whoosh noise on WOT, which ive heard on very quiet turbo exhausts on GTR's etc. Dyno after installing was quite a loss in power too. He got a H pipe made up which sounds alot better and gained the power back he lost
Nice work, in the future I suggest cutting the music on the exhaust sound clips.
😂
Agreed
Yupp
Yes like wat the f
And maybe a better mic
That double X pipe sounds seriously good.
That camaros exhaust is about the meanest thing I’ve ever heard. With a full system.
Add 10 x pipes in a row bare minimum
That thing sounds fking vicious. Great work guys!!!
Thank you!
That exhaust on that Camero sounds insanely Good! Wow.
Thank you!
Sounds like a straight piped Coyote. Sounds good though
It gives it more of a high pitched sound right ?
They sound nice but now you got me wondering how it would be if you did x pipe to h pipe or h pipe to x pipe.
The x pipe double I wounded how would it sound on my BMW e38 728i ?
Was everything else stock? Also, do you think the video sounds fairly accurate compared to in person? Sounds like a lot of drone but I'm guessing it's hard to capture the real sound on video.
Please make a video with single vs double h pipe this time
So you get space music when you go dual x pipes?
Couldn't say which exhaust sounds better since the video insisted on sounding like were in the club instead of a exhaust shop. Shut the music off during sound clips
I’m looking for a similar sounds to how you customized this. What resonator did you use?
Did the double X pipe make it louder?
What brand x pipes did you guys use
Sound is really distorted, looks like y'all did a great job on the Z. Would be nice to hear that beast rumble the way it's supposed to.

You're killing me with the music
We are newbie's to filming anything for sure lol
We have got better since then! Check out some of our newer videos!
@@dixiefabauto9830 I will for sure
@@dixiefabauto9830 Awesome. Music should *ONLY* be used as filler when you're speeding through something. (IE time-lapse or sped-up video)
Will adding a second x pipe to a single x pipe setup reduce any drone? Or significant volume? Or would going dual bottle resonators be a better choice?
In our experience, both would help.
Would anyone know if doing something like this would help create a better vacuum for more power do to the extra convergent point?
We saw an increase of 19 WHP and 30 ft lbs of TORQUE from this alone. We did no expect that.
If I did 2 x pipes on my straight piped v6 camaro would it tone down the rasp for me?
More thank likely.
i wish dyno test before/after
We actually got to do this a few weeks later. We didn't really know if we would see much at all, BUT we saw an increase of 19 WHP and 30 ft lbs of TORQUE!
What if they x-pipes were given a bit more distance in between? I’m interested in adding a second x to my exhaust🧐
The biggest problem with that on this particular car is there is just not enough room for that. It actually barley fit they way we did it.
Well the purpose of x pipes from what I’ve researched and learned (youtube certified knowledge) is to cause exhaust temps to reach a higher temperature helping them travel through the exhaust system a lot faster!

Overloading of your mike makes it impossible to tell what it actually sounds like. Fail.
If I add a dual X pipe to my exhaust , will that increese the sound ?
More than likely no... It will probably change the sound but I would not expect an increase in sound.
@@dixiefabauto9830 What kind of muffler that ZL1 had? Or it only had straight pipe?
@@hungary11 It has 2 (1 per side) 3 diameter, stainless steel, 9 inch long bottle / bullet resonators.
@@dixiefabauto9830 thank you for the response, where do I find those bullet resonators?
@@hungary11 We use 3 or 4 different brands, i believe these were from jones exhaust.
Dual x pipe, high flow cats, and a high flow resonator?
Yeah, pretty much.
How would this sound on a Silverado ? No cats double x pipe? 5.3

Yeah, building cars we know but we are new at using camera equipment haha. We will get it right!
However, drone did decrease be a fairly large margin inside the car.
All I could hear was TH-cam filler background music. We're we supposed to hear an exhaust? ;)

What x pipe did yu use and exhaust
We made the exhaust in house.
Damn!!!!!
I've often wondered if those eBay style x-pipes work well enough. There needs to be a flow test comparison video lol
They might, just like a horn or an instrument, different designs can make different sounds.

What mufflers is Kevin running on this?
12 inch stainless resonators on each side near the rear, close to the tips
Can’t hear with the music
4 X if you have to ask you can’t afford it
Audio quality is trash.
GM never made a ZL1 for that model they only made a Z28
That is not accurate Sir... Feel free to Google.

Wouldn't sound any different than 1. Waste of time, energy and, money.
The difference in tone was actually quite noticeable between one X and two X.
