Lexus ISF X-Force Exhaust Review

Review of the X-Force Cat Back Exhaust on my Lexus ISF with stock headers.

[@AliHamza-hw5rs]

Love these kinds of videos. Not many people making new videos on the isf, keep up the good work. 👌

[@ISFASTER]

Thank you! Glad you’re enjoying them! Lots more to come!

[@lpacalypse]

Thank you for the in depth review. I just purchased mine and I can't wait to install it. I was torn between this and the borla exhaust. Your review helped me a lot on my selection. Thanks again.

[@ISFASTER]

You’re welcome. I’m glad it helped! Enjoy!

[@dawnpoint]

Excellent video, great sound quality, and tons of variety in sound. I’d listen to just recordings of this car for fun.

[@ISFASTER]

Thanks! Glad you like it.

Thanks a ton man.All your videos are extremely informative .

[@ISFASTER]

You’re welcome! I’m glad to help!

[@martyconyers6189]

Thanks for the video. The exhaust system sounds good. I'm thinking of buying one for my IS F.

[@ISFASTER]

Thanks! It sure does, I bet you’ll enjoy it!

[@is4life593]

Good video explaining your exhaust!

[@ISFASTER]

I’m glad you enjoyed it!

[@masonfollansbee5527]

Sounds great man! Not gonna lie, been watching all of your videos for info on the IS-F. I've always had MR2/Celica/Supra but I want a car that is fast but still in the family and luxury. The IS-F checks all the boxes. Thanks for the videos. If you see a good IS-F under 100k miles for 20-25k let me know! I mean, I'm keeping an eye out (obviously) but if you see one, let me know. Keep up the good work! I'll watch your videos even after I get one! :D

[@ISFASTER]

Thanks. For that price and mileage range you’re probably looking at an earlier year ISF. Just keep and eye out on the car buying sites and even clublexus.com. If you find a decent one be sure to act fast!

[@jayb.4648]

Mason here’s one with 85k miles www.clublexus.com/forums/market/925174

[@2jzgabe868]

I have an is350 but an isf has always been my dream car, obviously can’t afford it but working on it lol

[@edgarcastellanos9852]

Me too bro💪🏽

[@ISFASTER]

Keep it up! It will be worth it!

[@ImJustMe555]

Used ISF's are going for less that $30k. I've seen them for as low as $18k and I've heard of people buying them for even less. So don't count yourself out. You may be able to get one.

[@xCkillaxC]

ImJustMe555 Yeah but those are high mileage ones

[@ImJustMe555]

120k on a Mercedes, BMW, Cadillac, or Lincoln is high and those cars will probably need a bunch of maintenance to make them reliable, but a Lexus/Toyota will still be I good shape at 120k. But, if mileage is really a concern for you there are plenty of 40k to 80k ISF's for between $21k and $25k.

[@eco8gator]

I love my 2012 Lexus ISF, nice vid!

[@ISFASTER]

Thank you!

[@2kscmax]

Great video, and sound quality Andrew! what camera are you using?

[@ISFASTER]

Thank you! iPhone XS

[@Anthony-dk7de]

I installed this today and honestly it’s like a mix of muffler/secondary cat delete and stock exhaust. Doing a muffler delete now 😃

[@ISFASTER]

I hope you enjoy it!

[@Unsuccesses]

Debating on this or the varex version , not sure which would be better as I don’t plan on getting aftermarket headers that I know of lol

[@esteve72]

Nice video and nice exhaust! Sounds really good and undeniably the best value in IS-F exhausts. I'll probably go with Borla myself...good value too and I like matching quad outlets/tips (just personal preference). Picking up 20+ whp with a simple catback, plus the improved sound, you can't go wrong with any of these exhausts!

[@ISFASTER]

Thank you! I would say the Borla is the second best value exhaust for the ISF. Also nice that you can get the RR-Racing Bazooka axle back portion of you wanna get crazy! 😁

[@esteve72]

@@ISFASTER Yeah, the Bazooka axle back would be too over the top for me! It's good to have options though, especially on such a rare platform.

[@ISFASTER]

Very true. Our choices are limited!

[@CCRtoyadventure]

To solve everybody's issues of getting an exhaust but trip about the extra spacing behind the stock muffler tips and highway drone. Get 3inch black in color Cherrybomb Extreme mufflers(fits perfect sideways to coverup the hole, pair it with a magnaflow resonated tru x pipe 2.5inch as a resonator. Rest of piping at 2.5inch from magnaflow to cherrybombs. Super minimal drone and sounds mean as hell with no rasp. That is my setup now and love it. 😎

[@CCRtoyadventure]

Cost for everything. Cherrybombs (x2): 50$ on amazon. Magnaflow tru xpipe resonator: 120-130$. Piping, hangers, and labor: 200$. Total cost: $480-500$. You wont be disappointed.

Thanks for your reply mate.

[@ISFASTER]

🙌🏻🙌🏻🙌🏻

[@Saji]

Nice video, I’ve enjoyed a few of your videos now. I just picked up a 2013 IS F 2 weeks ago and it had a muffler delete from the previous owner (everything else stock). The drone was terrible between 1500-2000 rpm under even slight load in any gear! I’m dailying this car and have a 2 year old in the back seat so I couldn’t deal with that. Took it to an exhaust shop 2 days after owning the car and put custom rear mufflers on which have gotten rid of the drone and the sound is much closer to stock now. But now I know in the the future I’ll go with the varex x-force catback thanks to your vid. I loved the flyby sounds and it seems from your comments that there isn’t too much drone. Question, does your catback system delete the centre muffler as well? So you just have the 4 cats after the headers?

[@ISFASTER]

Glad you like them. Yes, the Varex system should give you the best of both worlds. Check out a picture of the system online and you’ll see what it looks like.

[@colonluis9441]

Sounds nice I'm thinking about it it is much cheaper then the ones I've seen thanks nice to know we got options 🤔

[@ISFASTER]

Yes, I couldn’t believe how much cheaper it was compared to the other exhausts on the market. It’s help up well too!

[@julianski09]

Enjoyed the video mate! I have a borla for my isf and it sounds nearly the same as yours. It wakes the car up😁

[@ISFASTER]

No doubt! When hearing them next to each other to me the Borla sounds a little deeper. If you really want to go wild you could always put on the RR-Racing bazooka pipes since they’re made for your Borla.

[@julianski09]

Yeah I´ve thought about that^. The only problem is in my Country (Austria) the police is quite strict about tuning in general. So with the bazooka it might be way to loud🤔. But maybe i will give it a try😅

[@ISFASTER]

Haha! Yeah, it definitely is not subtle! 😆

[@Rwdsach]

Great video

[@ISFASTER]

Thank you!

[@jasonk2787]

I would sell my sti in a heartbeat for an ISF. Mazing car and have always wanted one since they came out. Hopefully one day I will get one.

[@ISFASTER]

I hope you’re able to get one too, they’re amazing!

[@LeeePowers]

I hope you get yours soon,or,just wait for the GSF to come down a little more. Personally, I'd rather have the 2URGSE swapped into my LS460.

[@colby3333]

The welds on the xforce look better then the stock exhaust welds!

[@compacheo603]

Would muffler delete/reso delete and replacing the tips yield same performance vs spending $$$ on a actual exhaust system ? Subbed for more content bro. Looking at one of these isF for me next year. Toyota reliability 🤘🏼 and sleeper

[@ISFASTER]

I don’t think you would get the same gains as an actual exhaust system. When comparing the two next to each other you’ll notice the exhaust flows much smoother on an aftermarket system as the piping doesn’t have any sharp angles or spots where the exhaust is crimped like on the stock system. Also, cat back systems may include a catalytic converter delete which helps with power.

[@jackflash588]

Compa Cheo broke nigga

[@Univers..]

Great video Andrew! How does the sound of the xforce compare to a muffler deleted ISF?

[@ISFASTER]

Thank you! I personally think it sounds better. I also like that extra power you’ll gain from this exhaust over just a stock muffler delete.

[@5.0_Lex_]

@@ISFASTER where did u get it for 600 bucks?? Did u post the link

[@ISFASTER]

I believe the price has went up but it was snailperformance.com

[@isfdrewski2611]

Have the X force with secondaries removed and have no complains cheapest exhaust out there for the car and sounds the best .. debating on removing the mufflers but scared it’ll be too loud

[@ISFASTER]

FULL SEND!!!!

[@integrasaurus]

sounds better than mine with my oem cats removed. do you have any cels?

[@ISFASTER]

No CELs

[@dspada67]

Hi from Australia, have you heard this exhaust with headers or primary cat delete? Do you think a tune and Intake is worth it for the gain cheers

[@ISFASTER]

I’ve seen videos of it with headers, sounds similar to a Joe Z setup with headers if you’ve heard that. If you want to get the most power from your car then the tune and tuned intake are the way to do it, I’m fine with my current setup.

[@panzerfaust375]

Hey man great vid. Was wondering if you could confirm for me that under the rear seats there is bolt holes for the middle seat belt. I intend to put is250/350 seats in but only if I can put a seatbelt for it. Thanks.

[@emmcee476]

Im looking to buy this system and would like to delete the fake stock tips and attach (either welded or clamped) dual tips to each muffler. Is there a set of tips that wont be too long and has been confirmed to work with the X-Force mufflers? It sounds like its only noticeably louder at WOT. Is that the case?

[@ISFASTER]

emm cee - there are a few people that have added real tips, some threads on Club Lexus about it. It’s definitely louder throughout the rev range over stock.

[@itheus]

Do you have any experience with borla catback? Namely i dun think i can access xforce in the uk. Kinda stuck with hks/h&s and borla

[@ISFASTER]

In normal form I think it sounds a bit deeper and not as loud as the x force.

[@roeanp]

Hey Andrew you know or recommend a good Performance Mod shop in orange country I can order my headers and exhaust to get installed? I appreciate any feedback thanks in advance

[@ISFASTER]

Hi, I actually don’t know any in Orange County. I’m more familiar with shops in San Diego. I bet if you asked on ClubLexus you will get some good leads on best places for install as there are a number of Orange County F cars.

[@RivaStyx]

So damn good and throaty ❤

[@TopRawMen]

How does the exhaust look from the rear of the car does it look like the Joez ,where you could see the pipes underneath? You can tell the car has an exhaust?

[@ISFASTER]

Yeah, you can see the pipes underneath just like you can with the Joe Z.

I’m thinking about doing this or just getting a muffler delete with branch resonators.

[@ISFASTER]

I hope those video helps you decide.

[@AImighty]

ISFASTER Thanks. Also how’s the drone?

[@ISFASTER]

That’s subjective to many people but to me there’s some while in 8th gear around 2000RPM going up slight grades, not too bad though. Other than that I don’t consider there to be any drone.

[@jackarteaga2808]

I don't know too much about cars but are those "shots" at 6:43 good? I think it sounds awesome! What are they call? And is the car suppose to do that? It seems nice in my opinion :) like a gun or something lol

That’s when you’re banging off the rev limiter and is the normal sound for this car. Yeah, sounds like full auto burst!

[@jackarteaga2808]

@@ISFASTER Is it the type of exhaust you put on. Or no matter what, the car can do it? :)

[@gsheverything_2716]

For the price, I'll say 👌👌👌

[@101TheKMan]

Hey Andrew. Just wondering if the exhaust overpowers that glorious intake cross over? Also has it got louder overtime?

[@ISFASTER]

You won’t hear the intake as much as stock. I think the exhaust quieted down from the first week or so of it being put on and has remained the same. It’s been over 3.5 years since it was installed so it’s a bit hard to remember, maybe I’ve just gotten used to it.

[@user-po8ds2qn7u]

It sounds good more of a rumble then the JoeZ PTS exhaust but i love my JoeZ exhaust except for that price difference 😐

[@ISFASTER]

I was going to get the Joe Z exhaust but then I found this and the price was too good to pass up!

[@user-po8ds2qn7u]

Yea great price for the F 👍 people always ask me how much was your exhaust like 😳

Depends on how sensitive your ears are but one could say there is some in the 1800-2000 range going slightly uphill in 8th gear.

The Varex mufflers may be able to tame it down a bit and get as close to stock as possible.

It’s louder than stock but I don’t think it’s annoying by any means. Your best bet is to find someone with a setup close to you and checking it out in person since exhaust noise is very subjective to each person.

[@82godoy]

$800! Geez, just cough up the extra $300 for the Borla.I found it online with a code for $1100 no tax free ship. That will really open it up.

[@ISFASTER]

Out of curiosity what does the Borla do better than this exhaust? From what I’ve seen there isn’t much of a difference in power gains between most of the cat back systems.

[@82godoy]

I would think you gain more power since you are deleting the restriction of the secondary catalytic converters. It also has a deeper more raspy sound. Weight reduction.

[@82godoy]

I thought your exhust was axle back. If you do have a cat back there is minimal difference since you deleted your secondary cats as well.

[@ISFASTER]

The X-Force exhaust is a cat back system so power gains are about the same.

[@101TheKMan]

Any drone/boominess with this set up?

[@ISFASTER]

That’s subjective depending on each individuals tolerance. For me I find there to be a little drone at ~2000RPM in 8th gear going up a slight grade on a freeway. Other than that I think it sounds great!

No doubt the headers are the best mod to extract power from our cars. Accepting any and all donations if that’s what the people want! 😆😎😁
