Great except for exhaust tips
I got the stainless dual side swept exhaust. It sounds good. Loud during excelleration. Quiet at idle. Not too loud when cruising. I believe it increased horsepower (or maybe it just sounds more powerful). My only complaint is I don't like the dinky little bolt on polished stainless tips. For this price tips should be welded on at factory and twice the length.
Corsa Exhaust for 1991 Corvette ZR1
Very pleased with this system. It looks and sounds great. Installation was a breeze but a helper makes it easier. I installed it using jack stands with no issues. The clamps provided are the best I've ever used. This is a much better exhaust than the B&B system on my 2008 Vette. There is no droning at cruising speed and the sound through the gears is awesome.
