I'd be looking for some Z06 Ti's if I were you. Failing that, I'd go down to Corsa touring.

You could get some Corsa Touring, B&B Route 66 or similar "quiet" aftermarket exhaust to run on the car. Sure wouldn't want to take off the headers.

Seems this is a common problem with people that add headers. By the time they add headers with one of the louder aftermarket exhausts, it's just too loud. (or they're just too old...lol)

Eventually I will add headers but at that point, I'm sure I'll be looking for a set of Ti exhausts.....

Corsa Touring is supposed to be almost a stock replacement with just a bit more kick WOT. If it WON'T make that much difference, the only thing left is to put your stock system back on (or the above mentioned stock Z06 system). There isn't anything else quieter.

Flame suit on.

I hear many recommending Ti's. I doubt if you would have gone with the Corsa indy's if you could stand the sound or restriction of the Ti's. I hear at least as many Z06 owners complain about the Ti's as I hear non-Z06 owners praising them. But then, that's why so many of the Ti's become available for non-Z06 owners. FWIW I did try Ti's briefly but also found them too quiet for my taste.

As for your question, I have noticed the same thing with my LT's and Borla Stinger combo on initial startup, but it's really only for less than 1 minute. That's when the garage door opens.

Good luck

Headers will make ANY exhaust system louder! Combine that with aftermarket mufflers and the tone will get louder. Stock mufflers will quiet a header car down with MAYBE a 5-10HP loss.

The Corsa Touring is not a complete catback (no X-pipe).

As for price, WCC is competitive. If you like the look of two big ovals, they also have an exclusive version:

An X-pipe might calm it down a little-but it won't be much

I would try an X-pipe first, and then if that's still too loud, the Corsa Touring.

Or, if you still have the stock exhaust, why not "test" that first.

I had Corsa Indy's with headers before changing cams. After the cam install, it was way too loud. Went to the tourings and it's a day and night difference. I was able to find someone locally who was willing to swap exhausts. I'm sure you'll be able to find takers for your Indy's

You don't. I don't hear much about Supermaxx, and guessed (incorrectly) that they were shorties.
