The quad tips are somewhat functional. The stock exhaust has 4 tips that exit out of the 4 diffuser tips. The diffuser tips have a small scoop on the back that scoops air from under the car, mixes it with the exhaust fumes, and runs it out through the bumper to avoid melting the bumper. Muffler delete sounds great. I recommend PPE headers and Joe Z exhaust.
Wow man, it's amazing how much better she sounds without the mufflers. I've always appreciated a low and deep rumble so this hits home for me. Great job awaking the passion from that exhaust.
Wow dude don’t ever get rid of this car , such a gem .. you should hear a basic is250 with indivia mid pipes and muffler Delete sounds like a skyline gtr no lie
This isn't a bad long term mod man. Mine has been deleted for several years now - and it sounds gorgeous. Not Equal Length Novel, but it's still quite nice.
Reminds me of when I took the mufflers off my 3.0R while swapping sway bars, it will definitely sound even better with the proper exhaust on it! Making me miss having a slightly obnoxious car, I am enjoying the quietness of the Crown though (for now).

Muffler delete can do a lot! I cut the muffler off of my 540i and just put a downpipe in his place and it sounded soooo much better. It did have a host of other frustrating problems and I'm glad to be rid of it, but I do miss the sound!
At 5:18, you can see where the exhaust flattens out... The same design on the SC430 but its crimped down even more.. Its down to a little over 1" believe it or not.. I originally thought it was to provide a little more backpressure for low-end torque. The exhaust was restrictive in a few other spots as well, but I addressed it with a custom true-dual exhaust, using universal magnaflow mufflers and kept the resonator. I found out that the car lost no power shortly after the work was done and the crimped spot at the Y was gone. The exhaust shop thought Toyota did this to make a little more room around the IRS/pumpkin, and allow that area of the exhaust to be closer to the car frame. Eventually I had a hole develop in one of my magnaflows due to bad welding, so I had it fixed. After listening to the exhaust, I wanted to try removing the resonator later on. Few months past that, and my 2009 SC430 was totaled on the front, so the exhaust was cut off and moved to my 2006 SC430 replacement that was actually in far better shape and in blue which is not the easiest to find. When the shop moved the exhaust over, the modified a few bends for better flow, removed the resonator, and then I had the install single chamber Flowmasters.. lol.. It fucking sounded unbelievable, and when I left the shop a couple of years ago I was certain I was going back to have them install a new resonator, but I have still not had it done yet. The car is no longer a daily driver, and I use it for pleasure and have played around with mods. One of these days I need to put up a video of the exhaust - its absolutely ridiculous and catches too much attention and as much as I enjoy it the drone is overwhelming when the top is down... Its actually a good deal louder than the car was without any mufflers. I cannot imagine what these flowmasters would sound like on the larger ISF 5.0 engine with no resonator. I kept the totaled 2009 and parted it out.. I have the power train and IRS aside with the engine on a stand, and working on improving the older 3UZ 4.3 V8. Picking up stronger and longer rods, and better pistons to make something that it more in the 4.7 to 5.0 range. All the other obvious intake and head/valve work, trans and torque converter, PPE headers, etc, and then finding a way to mount a universal turbo/intercooler kit on it, but nothing over 6-8psi. The current 2006 model has some mods and its not too much over 300hp but definitely faster than stock. We also have a BMW 328 X-drive, which is currently at 78k and when it gets closer to 100k, I am going to pick up an ISF to replace it.. I have been eye-balling the listings, and recently found one for around 19-20K with 130k or so miles in great shape but with a few dings and few scratches on the paint.
Fun fact: I'm 186 cm tall and i barely fit in the driver seat of my grandad is250, i hit the roof. If you are 190cm tall and over you will not be able to drive comforly
So, cars have passive air flow vents in the rear quarter panels. Leaving the exhaust to vent under the car will draw CO into the interior. Probably not a smart idea to run it that way.
Honestly a big fan of the two into one axle dump. Just need to delete all the stock cats and do a turn down on the dump and you have maximum weight loss with great in cabin sound and a car that's actually not all that loud from far away. Also it still has exhaust tips so folks don't know you've gone full weight loss lol
jon schlegel i’m going to work until i can pay half of it and my dad is going to pay the other half other than that i’m going to be paying for all things im going to do to it
Congrats! I have low milage 2014 black ISF and love it all the way 😍 Sikky headers and JoeZ is my recommendation - i have it and it's stunning. It's great reliable car 😎 what's your ODO now?
I’m sure you might have done something already but if your getting a full kit it won’t matter but I had to secure the pipe to the cross bar that’s right under the pipe On Mine the pipe would bounce and smack the bottom of the car. Then I put on the borla kit and left the stock headers.
I messaged the person selling the car but I didn’t have time to go to knoxville to drive it sadly :( I was thinking about buying this exact car..... but as we can all tell it was too late...
If straight pipe is run exiting under the rear bumper, it will then help to minimize drone. Having the resonator opened at the center of the chassis under the car will, of course, is not good at all.
Hi kurt and good morning Love your isf awesome car.Id live to get one myself I've dome some research on them.You should go with the PPE headers compared to the sicky headers.Its very labor intensive for the headers the guys at sicky put a video out on changing out the headers.Glad your having fun with the car and happy driving.
Pretty soft still. I also deleted my resonator and still sounded too quiet. Going to delete my secondary cats hopefully it’s enough sound till I get my headers lol
Interesting, my car has a resonator delete I believe and instead of deep, bassy sounds, it absolutely shrieks as it climbs up the rev range. IDK which i like better hm..
sorry not too good at the mechanical parts of a car, i want my isf to sound better, but why isnt muffler delete a good option for long term use? does it damage anything or what?
The M156 in the C63 is a beast, one of the few cars that clearly sounds better than the ISF. To hear a M156 bark to life on startup is to get goosebumps! As far as reliability, hands down Lexus.

I don't understand how all these TH-camrs take all this time to do a video but don't do proper research to give the right info. This guy should have done a bit more research about why the exhaust tips are there for before saying that they're "fake" or "for aesthetics only"
Both primary and secondary cats are upstream, wont make any difference in emissions, however larger risk of exhaust fumes pulled in through the trunk vents, yes.
Axel back waste of money no performance benefit and not that much louder that stock. Headers by far give you the biggest increase in actual HP. When headers are combined with catback exhaust that when you gain a significant amount of horsepower and torque as well as serious sounding exhaust. If you just do headers and leave stock exhaust you get bump in hp not as much if with went with catback but your level will be more muted. Also stock manifolds are know for cracking. I've owed my 2011 ISF since it was new also 10yrs now. I've been FBO for 9yrs and Tuned for last several yrs. No issues with PPE headers or JoeZ exhaust.
@@is4life862 I've watched all of his videos and communicated with him several time regarding his videos here on TH-cam. He has mastered launching his car in 1/8 mile races. He wins most of his race because he has tons of seat time and knows how to launch his car. He himself state he has significant amount of time at his local track. It doesn't mean you can duplicate his feats? unless you spend a lot of time at track like he does or did he was selling his ISF but he was there nearly weakly. I'm not some numb I'm 56yr old, have been driving sports cars for 38yrs have owned all sorts of performance cars from America muscle, European, and JDM cars. I've owned my 2011 ISF since Is was brand new nearly 10yrs agos. I'm FBO RR Racing Tune and Tuned intake running E30 blend figs engineering RRRACING Sikky compents as well as two suspension KWv3 coilovers and Airlift3H. Currently on Airlift 3H. With these mods it allows ISF to stay competitive against modern cars such as s550 Mustang GT, RCF, SS Camaro, Stingray C7 vettes, GSF, 392 Chargers even stock M4's and other modern and older performance cars. A stock ISF does not stand chance against any of these cars if driver of newer or older higher hp car has equal skill level driver to driver. Its driver that's the most important part of any cat no matter hp or tech it has but some times it can just be pure hp advantage. But when facing opponent of equal skill whether stock or FBO it becomes now which car is more capable. If you like to cruise along with occasional WOT. then back to cruising along or happy with performance of stock ISF which is still a very capable and fun cars to drive on street or track yeah then stock is cool and there or advantage of remaining stock. But if your competitive and want to maximize the cars performance potential then by all means do what you like. FBO or just catback, perhaps FBO plus Tune. Especially if you racing your car at 1/4,1/2, 1 mile events, runway races or highway pulls against modern cars a stock ISF wouldn't stand chance against these newer cars with equal drivers. Now FBO Tune and Tuned intake ISF can be extremely competitive against cars that have 12 plus yrs newer tech and hp advantage such launch control, awd, higher hp then stock ISF. Most of these newer cars all start around 450hp and go up from there in todays performance cars. So it depends what you want to do your expectations. Can experience driver in stock ISF beat inexperienced diver in newer or higher hp car? yes absolutely. But it's driver skill level that won not car. If Two experience drivers with same skill level race let say stock ISF against any modern higher hp car like let say 10 speed automatic paddle shifter S550 479hp and 442tq with Ford cold air performance kit it's just $1200 option 90% of owner have them. Against 416hp and 371tq on stock ISF doing roll race on highway up top the ISF will do well but just not enough to hold off S550 Mustang. Now FBO tuned ISF running against FBO s550 thats race. Just look here on TH-cam and watch race between ISF running these newer cars and see how well FBO Tune some with E85 do against these same s550 FBO Mustang and others. They are winning races especially on highways, runway and mile races events. That where ISF shines up top past 120mph mark up to 170mph or higher if you have speed limiter removes, it just pulls and pulls when FBO and Tuned. So it all depends on what your goals are. Some owner like to keep their cars relatively stock and that's cool I get. While others like to mod their cars, they are looking to maximize their cars potential. So to say you don't need to be FBO depends on owner expectations and goals are for his or her car. But to think stock ISF can keep up with new cars with equal drivers with same skill sets is interesting. Like I said I've owned my ISF for nearly 10yrs I know what's its capable of both in stock form with just JoeZ catback back, then PPE headers and JoeZ exhaust, now RR Racing Tune and Tuned intake that comes with larger MAF housings to allow for larger volume of air being pushed into motor using 7in K&N cone Velocity stack air filter along with E85. Believe me when I say there is night and day difference between two. Add RRRACING S/C now your in whole different category more in supercar territory with hp of 530hp to 780hp. So it's all about expectations and goals of individual owner👍.
The y-pipe is the only thing that's "wrong" with the stock exhaust. A true dual system with h-pipe sounds the best, to me. Greddy is king: th-cam.com/video/LaY1rfk9Oh4/w-d-xo.html
Anybody switch from strictly driving manuals to getting one of these? I always feel like life sucks when I drive an automatic but I like this car. I just don’t want to get it and immediately want to sell it. I usually feel less in control, especially when they shift in corners but, I guess the paddle shifters help?? Idk. Any opinions??
Personally, I don't have a problem with automatic cars as long as the automatic is good. The old slush boxes are still around in many cars and absolutely awful to drive, but when you drive a modern auto that is actually good, like this one, you don't think about the loss of the stick nearly as much. This auto is great, and the fact that it came out in 2008 is mind blowing to me.

@@hamsterbrigade Hardly! I will buy an ISF soon. Great car but its character's different from the AMG. The Lexus somehow isn't about the noisy bombast associated with the AMG.

also, if someone was to hit you from behind, a real exhaust wouldn't crumple on impact all the way to the transmission etc.
So removing the muffler can cause it to melt or what?

For my muffler delete had to cut them off with a saw, nice that you could do it without cutting anything.
You have an isf and had to cut it off? Axleback portion is bolted. Or did u mean the hangers? I had to cut 2 of the 4 that were connected to muffs
Lexus stopped making the ISF. Did you all see the unveiling for this upcoming year? Not a fan of the new one...sick exhaust by the way!
I own an isf, and i find that muffler delete on the isf sounds the best. Idk why. The pitch is much higher
Exactly what I did. Sounds beast besides the drone .
I watched the Sikky headers install video last week...I'm no longer interested in putting headers on now hahaha
Yeah............. about that...
And it's way worse than that video shows... one of the best upgrades you can do to the ISF though so well worth it.
This reminds me of those Downshiftings from StraightPipes video with his then ISF🔥🔥🔥🔥
supporting the channel
Gut the header cats. Once gutted it has almost the same flow rate as the PPE headers
You also gain 25 hp cuz the stock headers are very restrictive
yea my bro did the gut it does make more power. similar to ppe header
You’ll get a engine light tho?
Good luck with installing headers cuz it's very Labour intensive, barely any room to install.
You doing the steering computer next? 2013-2014 steering computer is supposed to be the best, but 2011-2012 is a big upgrade as well.
yea the exhaust (Borla) will actually create power as it deletes the 2 cats under the car so your about to have a blast had my isf for 5 years

Does it change the driving characteristics? The weight ratio front to back might be be changed significantly if those mufflers are as you say weighty.
The next mod I highly suggest installing is the rr racing usrs, improves the handling of the car drastically

He wins most of his race because he has tons of seat time and knows how to launch his car. He himself state he has significant amount of time at his local track. It doesn't mean you can duplicate his feats? unless you spend a lot of time at track like he does or did he was selling his ISF but he was there nearly weakly.
I'm not some numb I'm 56yr old, have been driving sports cars for 38yrs have owned all sorts of performance cars from America muscle, European, and JDM cars. I've owned my 2011 ISF since Is was brand new nearly 10yrs agos. I'm FBO RR Racing Tune and Tuned intake running E30 blend figs engineering RRRACING Sikky compents as well as two suspension KWv3 coilovers and Airlift3H. Currently on Airlift 3H. With these mods it allows ISF to stay competitive against modern cars such as s550 Mustang GT, RCF, SS Camaro, Stingray C7 vettes, GSF, 392 Chargers even stock M4's and other modern and older performance cars. A stock ISF does not stand chance against any of these cars if driver of newer or older higher hp car has equal skill level driver to driver. Its driver that's the most important part of any cat no matter hp or tech it has but some times it can just be pure hp advantage.
But when facing opponent of equal skill whether stock or FBO it becomes now which car is more capable. If you like to cruise along with occasional WOT. then back to cruising along or happy with performance of stock ISF which is still a very capable and fun cars to drive on street or track yeah then stock is cool and there or advantage of remaining stock. But if your competitive and want to maximize the cars performance potential then by all means do what you like. FBO or just catback, perhaps FBO plus Tune. Especially if you racing your car at 1/4,1/2, 1 mile events, runway races or highway pulls against modern cars a stock ISF wouldn't stand chance against these newer cars with equal drivers.
Now FBO Tune and Tuned intake ISF can be extremely competitive against cars that have 12 plus yrs newer tech and hp advantage such launch control, awd, higher hp then stock ISF. Most of these newer cars all start around 450hp and go up from there in todays performance cars. So it depends what you want to do your expectations. Can experience driver in stock ISF beat inexperienced diver in newer or higher hp car? yes absolutely. But it's driver skill level that won not car. If Two experience drivers with same skill level race let say stock ISF against any modern higher hp car like let say 10 speed automatic paddle shifter S550 479hp and 442tq with Ford cold air performance kit it's just $1200 option 90% of owner have them. Against 416hp and 371tq on stock ISF doing roll race on highway up top the ISF will do well but just not enough to hold off S550 Mustang. Now FBO tuned ISF running against FBO s550 thats race. Just look here on TH-cam and watch race between ISF running these newer cars and see how well FBO Tune some with E85 do against these same s550 FBO Mustang and others. They are winning races especially on highways, runway and mile races events. That where ISF shines up top past 120mph mark up to 170mph or higher if you have speed limiter removes, it just pulls and pulls when FBO and Tuned.
So it all depends on what your goals are. Some owner like to keep their cars relatively stock and that's cool I get. While others like to mod their cars, they are looking to maximize their cars potential. So to say you don't need to be FBO depends on owner expectations and goals are for his or her car. But to think stock ISF can keep up with new cars with equal drivers with same skill sets is interesting. Like I said I've owned my ISF for nearly 10yrs I know what's its capable of both in stock form with just JoeZ catback back, then PPE headers and JoeZ exhaust, now RR Racing Tune and Tuned intake that comes with larger MAF housings to allow for larger volume of air being pushed into motor using 7in K&N cone Velocity stack air filter along with E85. Believe me when I say there is night and day difference between two. Add RRRACING S/C now your in whole different category more in supercar territory with hp of 530hp to 780hp. So it's all about expectations and goals of individual owner👍.
@@TheDavcrz5 I take your word for it holy cow 😆
I kind of think it sounds better stock, which is a first, at least over video, if mainly because of induction sound
The y-pipe is the only thing that's "wrong" with the stock exhaust. A true dual system with h-pipe sounds the best, to me.

Anybody switch from strictly driving manuals to getting one of these? I always feel like life sucks when I drive an automatic but I like this car. I just don’t want to get it and immediately want to sell it. I usually feel less in control, especially when they shift in corners but, I guess the paddle shifters help?? Idk. Any opinions??
Personally, I don't have a problem with automatic cars as long as the automatic is good. The old slush boxes are still around in many cars and absolutely awful to drive, but when you drive a modern auto that is actually good, like this one, you don't think about the loss of the stick nearly as much. This auto is great, and the fact that it came out in 2008 is mind blowing to me.
Ur isf looks dope
Mic can't do it justice. Needs to be heard in real life.
She purrs
brRRRRR BEEP!
Is it legal?
Yes muffler deletes are fine. Cat deletes are illegal.
It shifts like it has a DSG transmission
I'm picky and broke so my exhaust is gonna stock for a while
It's amazing to me that Lexus engineers set out to build this high performance car and when they got to the exhaust they were like eh it's fine.
It is fine actually. This is not a riced out Honda Civic with an AutoZone muffler.
It’s fine. Just can be made better to suit the V8
Frying ur diff man, get a proper exhaust asap
Get a straight pipe it’ll sound the same as an exhaust
hello drone
Next: cat delete
Linus?
Dude! That’s what i freaking thought, Linus Car Tips. Long lost twin?
How to cook and set fire to your car from the heat. You need a pipe to direct it out.
Sounds too much like an AMG...
Tf is that suppose to mean
@@RAMTEE He's basically flagging himself as an euro snob. Cause the company that made the LFA doesn't know how to make cars sound good, only the Europeans know how to do that. I feel like Euro snobs need to go to Germany and see how the cars they covet are viewed like basic transportation there cause there are so many of them. The taxi cabs in Munich were BMW 7 series.
@@hamsterbrigade Hardly! I will buy an ISF soon. Great car but its character's different from the AMG. The Lexus somehow isn't about the noisy bombast associated with the AMG. Seems to me it's more about a quieter, higher-pitched deployment of V8 power. Kind of like in the same way the the Nissan GTR six-pot sounds markedly different from the M3 straight six...and both are great icons. Ive edited my original comment to reflect this more accurately...
Dude it says speed limit is 45mph not 95mph.. what are you 18 years old taking off your mufflers 😂 such a teenie weenie
Meh it's pretty underwhelming. As long as you like it though!
And on the next episode he'll be replacing the engine because he f***** up the compression ratio

Hope you get a real exhaust soon cause it’s a shame how you disrespect an F like that. From a fellow IsF owner.
Owner of ISF since 2011, totally agree w Ronald. How the hell you disrespect an F like that man. Get a real exhaust then we talk.
@@vincentlee2865 He removed 2 bolts and 2 stock mufflers for a free experiment. Stated it was temporary 3 times then said he has aftermarket headers/full exhaust on the way. Did you watch? You guys saying you're ISF owners doesn't help either
@@BitcoinTo100K what a bunch oh whiney bimbos
lmao you guys are giving the F community a bad name. He did a temporary muffler delete and you're complaining that he "DiSrEsPeCtEd tHe F"... It sounds pretty good and like he said many times he's getting an exhaust.
You drive a Walmart grocery getter dude. Nobody cares.
