Wow, they look awesome!

Quick question - do you have aftermarket exhausts on the LT4's? I have a Grand Sport and as good as the stock exhaust is supposed to be (flow wise), it makes my Grand Sport seem "ho hum" driving it, compared to the cackling and extra noise of the LT5 with stock exhaust. I like the looks of the stock exhaust, but I think the GS needs more character. Thinking a Corsa with black tips (and I would paint the muffler cans black) would solve the problem.

Thanks! I haven’t had corsa exhaust but I’ve had borla and magnaflow and I couldn’t tell any performance gains. The collector car has magnaflow now. Both exhaust systems have a drone in 6th gear that drives me nuts

Based on my own experience with a Corsa on my Yellow ZR-1, I think you would love the Corsa on your LT4's. ....No drone. The Corsa isn't cheap, but I really like it.

On your yellow LT4, their black tips would look nice! Corsa used to call them "black diamond" tips, but they now call them "PVD" for "physical vapor deposition". Looks like black chrome. Then if you take a good high quality high heat exhaust paint, scuff up the muffler cans and outlets prior to the tips, you can mimic the factory look.

Regardless of all the exhaust manufacturers claims, I wouldn't buy the exhaust based on HP gains. At least not that alone...I don't think one would notice much of a difference.

For the stock ZR-1's, I personally like the sound of the factory exhaust and with such a sweet car as yours would probably just leave it that way...but that is just me. Enjoy your new car.

Welcome to keeping the legend alive. You were off to a good start already owning a C4 and understanding their special quirks.
