Lexus ISF exhaust compilation I've owned. Borla catback and bazooka and PPE headers etc 

If you have stock headers it will be a good sound! With headers it will be too much. That's why I currently run a xforce varex with headers.

Thanks! Both the F's had Tom's replica diffuser. The white ISF had front lexon lip and replica cf side skirts. The silver F had bayson r front ebay lip, and ebay skirts. Both had vinyl wrapped roofs and 35% tint.

Hello Dom, happy to offer my advice. ISF is definitely a bit muted compared to an M car off the showroom floor, but there's easy ways to improve it. First off I recommend at least a 2010, or better yet an 11+. That will give you the LSD, and in the 11+ the updated headlights, better suspension for handling and comfort, wider wheels, bluetooth and other minor bits. The 11 ISF matched the lighter E92(with semi slicks) at VIR exactly just with the LSD/suspension upgrade over the 08-09, so it may feel muted but the ability is there. If you get an 08-09 the LSD is less than a $2k upgrade but if you just want to daily drive the car is plenty of fun still. Next I'd recommend first modification be the lower control arm bushing. They are under $400 and come from RR Racing as the USRS or Figs has a 90 durometer option as well. Both increase handling and braking stability and offer less front tire wear. They are more useful than a front sway bar. Making the jump immediately to headers and full exhaust and tune can definitely be pricey, can smell bad, and as seen in my case drone can be difficult to deal with for a daily driver. I would honestly just do LCA bushings, catback exhaust, a tune, and better/lighter/wider wheels and tires. Headers you can always do later, they give the best HP bump and are a good replacement as the stock manifolds tend to crack as they get up in age/miles. To give you my experience with drag slip times and the power numbers I've seen: stock ~350whp, 12.7-13 quarter. With my 2008 silver one I ran a 12.7 at 112 with borla catback, which is supposed to add ~15-20 whp. Adding RR Racing tune and better summer tires I got it down to a 12.3 at 115. Roll racing I've kept up with headers F cars, but not headers/exhaust, those I lost by a car at most. Not sure of the WHP improvement, maybe 10whp, but it is felt. I have not run my 12 ISF yet, but with headers/tune/intake/catback/summers my seller got 11.9, and even 11.7 on slicks, I'm hoping with some improvements I can beat or at least match it come spring time. Headers alone offer about 30whp and maxed out NA they should be at 420-430whp, just scratching the 500 crank number. They are great cars and relatively cheap to own. I avg 20-21 mpg and if I baby it on trips I can crank out 28-29 mpg. My 12 has HKS coilovers, figs 90 bushings, rays gram light 57cr wheels, rr racing tune and tuned intake, ppe headers, borla catback, and Michelin P4S in front and PSS in rear, lexon front lip and replica side skirts/diffuser. I have other videos of both cars also. Merry Christmas and good luck in your search!

zachary paris you’re absolutely right. Of all the ones I’ve had including my current Xforce Varex+ppe, I’ve only liked it and the Borla muffler delete with stock headers, nothing else.

@@valdaviper1 did you have the cats smashed out of the stock headers?

@@sircefiro no on my silver F I always kept the headers intact. On the white F I had ppe unequal length headers which are catless.

@@valdaviper1 Cheers man, I'm in NZ, it's expensive to import the headers at the moment so is pretty bad hp for the money

​@@sircefirodid you get the headers in the end , I'm in NZ too , just wondering how much the unequal headers were to land here ... just looking to buy now , looking at 2011 or later ,,, hopefully get later model ,, low km , .. mines not going be daily driver ( got gs460 for that). . This just a toy sorta , but am going to do headers , exhaust and air intake , plus lower steering .. plus tune .. you done any mods on yours ? any probs or ?? do U daily drive yours ?

tom's replica. Thanks! seems like everyone has it now, I kind of want to get rid of it.

I loved the stock headers with Borla with the mufflers straight piped. Was loud without being too much, and very tolerable drone. Adding headers amplifies noise and drone much more. Personally I think even regular Borla drones a bit much for me, I think due to the metal being thin and thus light. I hate drone but found the Borla with mufflers off, but stock headers was tolerable. I drove MD-FL-MD within 4 days and didn't mind it at all.

valdaviper1 thanks for your view. I have been told similar things abt the drone. I opted for the hayward and scott catback set up at the end :) waiting for it to arrive now!

@@itheus No worries, sorry it took me a week to reply, I seem to have missed quite a few notifications lately. Hope you enjoy, I have heard great things about that exhaust!

Is it louder now? How’s the drone? I’m planning to go this route

DaggerX15 I run Rays Gramlight 57CR 19x9.5+45 square. I just installed the Xforce Varex dual mode system so it’s both loud and quiet. Love it

Those are SpecD in smoked red. Sorry but links don’t copy well to RU-vid. Check my other videos for more in depth comparison of them vs the more popular Vland

Not sure, I had to go through 3 local muffler shops until one found me a set that fit, but they didn't do much for me ultimately.

I purchased it when they were readily available. But they’re discontinued now.

@@valdaviper1 did it come with the mufflers when you bought it?

@@Jrob94 yes. I ran it like that about a year but it really wasn’t much louder than OEM. Sounded like it should have from the dealer. Then I straight piped the mufflers and loved it like that for 2 years until I got my next F and it had headers and borla as well.

@@valdaviper1 I see rr racing has 2 borla catback systems but I’m not sure if it’s the one you have. One has the catalytic converters and rear mufflers (magnaflow) still on and the bazooka has two catalytic converters with the rear mufflers deleted.

@@Jrob94 RR racing makes a catback very similar to the Borla design. The difference is both of their systems have quad tips at the back replacing the OEM oval tips. With Borla the tips end before the “fake” OEM tips start. They also offer two options, magnaflow mufflers, which are slightly louder than the borla mufflers, and the bazooka, which deletes the mufflers and gives you straight piped at the back and also quad tips. Both axleback pieces from their catbacks you can add to a regular borla catback. When I deleted my borla mufflers I tried the magnaflow mufflers with quad tips, but didn’t like the bigger tips rubbing on my diffuser, and it wasn’t much louder than the borla mufflers. When I straight piped the mufflers I kept OEM tips. A lot of combinations. Every catback for the ISF like the Borla, Xforce, Joez, PPE, Greddy, etc. all delete the secondary cats and offer larger piping, thus the performance benefits for all are largely the same. There are also valved options which are helpful if you have headers.

What car do you drive?
