Is anyone here full catless with just an axleback?
I currently have an invidia axle back and have my secondary cats deleted.... planning to gut the primary cats within a week or so.
Headers and resonator will remain stock.

Just curious on sound change with a primary cat delete added to this....

Thanks!

 

Don't care about breaking the law?

 

This doesn't really answer my question now does it?

 

Well speaking for myself........no I don't.

 

Im not sure about Up there! But down here if you want to go catless, you have to be really tight with your mechanic. Otherwise you cant pass inspection. Youll also have to tolerate a gasoline smell since your cats are now gone.

I cant speak for the 2is, but my 435 is catless and it made the car sound 100x sexier. I say do it!

 

Its fine here, I literally called up one of the local shops and explained what I want, and what's already done and got a quote and everything lol.

I've heard +/- about it, but I'll give it a shot, since I already got CEL eliminators haha

 

that's gonna be loud af. people will be able to hear you from a block away, just sayin

 

Definitely keep the resonator stock. I ran a bunch of setups and have now finally ended with Mazurri Headers (Catless), Stock mid pipe (including 2 cats and 1 resonator), and a muffler delete, and it sounds the best out of every single set up. I ran full catless, full cat, half cats, everything you name it haha. This set up has no rasp essentially and is VERY loud. I love it. I would consider maybe removing the secondary cats with this set up, but i'm going to hold off for a while. The last set up didn't work to well with no cats because i was completely true dual from headers to exhaust tips and essentially straight piped, just had two straight through flow resonators. But I think when I put the stock mid pipe back in on this set up, it made a huge difference because the exhaust gases merge and cancel out sounds, and I have the stock resonator which was literally designed specifically by lexus to tune out the 4GR-FSE bad sounding exhaust notes.

 

Ended up deleting my resonator.

Now my exhaust is: Primary cats -> straight -> Invidia axleback

Secondary cats and resonator are gone! Nice and loud.

 

Post a video of your setup. Unless we meet again on the road lol. I'm the black is350 with exhaust that you met a while back in the summer hahah.

 

I got a 2012 is350. I have a muffler delete and a 1792 bottle style vibrant resonator. It sounds amazing but I Wana do a catless down pipe. Is it possible to do a catless downpipe on my car and how would it sound? Could I make it pop, bang and burble without a catless downpipe and what would I have to do
