Here is a clip of my car.... with some new mods the exhaust is almost unbearable. Should I get high flow cats or put a stock Z06 Catback on and ditch the Corsa?!?!

Too Loud

I almost think this clip doesn't do it justice, IMO it's obnoxious.

I wouldn't like that either. But if it makes you feel better, I also want a subdued exhaust-- so you've helped me learn what NOT to buy. Good luck.

I liked the Corsa a lot until the headers/x-pipe. If my car had manifolds and cats I would definitely keep the Corsa..

You should've rev'd it up a bit.

The Corsa is very nice. I'd keep it and go with cats. Ditch the ORX.

...and the cam sounds nice and lopey.

That is with heads/cam/headers and offroad pipe.

I'm not sure if this helps much, but you might try these header inserts in your collectors. They've been known to really cut down on ridiculous noise. Racers use them in tandem with a race muffler to really reduce noise without the horsepower loss. You might be able to use these, and save money by not having to reinvest in more exhaust components. I know there's info here on LS1Tech about them. So you might also do a search. Here's the link & site that goes into detail about them:

I have FLP's with no cats and Corsa Indy's. I thought it was a bit loud at first, but I have gotten used to it and actually like it now. Still able to hear the radio and hold a conversation easily. And when you get on the gas it ceratinly doesn't sound wussy. Drive it for a couple weeks and then decide if you want something more tame. You could also stick some cheap resonators in there. Less HP drop than cats. Should make it quieter.

i had similar problem, actually had neighbors complain...replaced Corsa with stock ZO6 Ti and everyone is now happy...i can hear my stereo again...

I have FLP headers + no cats + Z06 mufflers and its QUIET unless I want it to be loud (WOT). It is a normal sounding car when not on it.

You might try the TPIS exhaust. I've heard it in person and its got a deep mellow tone to it without cats. However I don't how it compares to the ZO6 Ti

Where could I see a pic of the Z06 Ti mufflers, and what is the part number?

That sounds badass. Post up a video of you reving it up, or getting on it!!

Sounds like an LS1 without cats. Install some cats and that rasp will go away.

A catted X should quiet it some and kill the rasp while also cleaning up the sound as well. Whatever you do, do not get the Car Chemistry Baffles to reduce the sound unless you want your dyno chart to look like this...........................Open QTEC vs Full Exhaust w CC Baffle.

Sounds good. I want to hear what it sounds like in car.
