I've heard some Camaros have this as well, lol.

I don't believe so. Even a header install with high flow cats and cat back exhaust doesn't effect the power train warranty unless you through in a tune.....just my understanding however.

Muffler delete is the only mod I have so far. Not loud at all, acutally kinda quiet. No change in performance, I did start averaging .1mpg better fuel economy...

ZL1? Sweet, didnt know.

Does it open at take off and close at high speed?

-or-

Does it stay closed at take off and open at high speed? (my vote)



Apparently, Chevrolet gets it.

It's an Inexpensive way to achieve a nice V8 rumble and lose the factory muffler weight.

Dumb question dept: Does the muffler delete have any effect at the DEQ for smog check when renewing license plates?

Apparently, Chevrolet gets it.
Works like the vette. Not sure of actual throttle % and rpm, though. Most of us pulled the fuse to it so it stays open all the time, though. Or you can buy a Mild to Wild switch w/remote so you can control it yourself, or program it to a home link switch.
BTW, NPP exhaust is an option on SS and some, if not all V6 models.

This is what I'm leaning towards. I hear the J pipes practically eliminate drone.

I love the sound and look of the muffler delete on my 2010 SS. People ask what exhaust package I'm running when they hear it. Sounds great, IMO. One of the best and cheapest mods you can do to improve the exhaust tone. Two words: DO IT

Only person I ever had tell me that they didn't like my straight pipe was a friend of mine with an ls3 camaro that paid over 1K for a big name catback and they sounded nearly the same ...


I have since added longtube headers with no cats, still sounds perfectly great to me

But OP is from "EU" which I assume stands for European Union.
Cars in Europe have different equipment requirements.

I did the muffler delete and I got so sick of the drone! It was bad from 1900 to 2200 rpm's. At first I thought I would get used to it because the sound was so much better over stock but after some time I just didn't like it. So I went full headers and cb system and now I'm a happy camper.
