Youtube hasn't given me any examples beyond some ISF cars with the same delete. I already have a muffler delete and plan to bump it up with a cat delete as well, ill try and get video for you.

If anyone has an IS350 with just the cats nd mufflers deleted, feel free to post your vid, I'd like to see what I'm getting myself into :3

 

I believe deleting cats doesn't make that much of a difference o_o

If it's any help, I have a RESONATOR and muffler delete on an IS250 lol

 

I've been debating on an exhaust delete too. Just haven't made my mind up enough to make the commitment.

 

One thing is for sure, even just a muffler delete makes this car sound sexier. A nice v8 exhaust note with no drone. Lexus did a great job making this car

 

Here you ladies go!

Those of you with muffler delete on an IS250. Are you all deleting the rear most muffler before the exhaust tip? I've been wanting to remove those not for sound purposes but for scraping purposes. I'm low to the ground and tired of hearing my muffler scrape.

My exhaust shop said if I cut those out my car will sound like crap.

Are you all putting aftermarket exhaust on or aftermarket mufflers?

 

I thought you were selling your IS xD
You can just get a shop to hack off those giant mufflers and weld in straight pipes w/ tips in their place. It would sound like the cars in the vids

I went a different route and installed a cutout, but that wouldn't help your situation

I thought removing muffler or other important part of exhaust system could damage your engine and loose power?

I heard mixed advise on this issue, could someone shim in?

 

Do you have cutouts installed too? , sounds amazing !

 

Yea, my mufflers aren't technically "deleted", but I have a cutout replacing my resonator so the sound is bypassing my mufflers (and resonator is removed).

 

No, in fact unless you have a check engine light on there's no damage being done...but different systems have different losses or gains.


After deleting just the axle back mufflers and the 2 secondary cats my car has greatly increased in power, shifting, and sound

 

Is this setup just a cat & muffler delete?
