I run Corsa on a couple of vehicles ('98 Z and '00 C5). Besides the excellent fit/finish I really like the two "personalities" of these systems. It's not to loud during normal driving so you can carry on a conversation with your passenger without yelling while driving down the highway. It's totally different when the RPMs start to climb and you are rowing through the gears. Very nice, aggressive sound at that point. One other good feature is the tips. You really have to see the tips!

Hope this helps,

I have one (yeah, it's an LT1) and I like it. Good build quality, very very very easy installation (you could do it one handed ). Stainless, too, unlike the piece of crap Flowmaster that rotted out. The sound is pretty loud and it does drone, but that probably has more to do with my 2.73s than anything.

Got mine from TByrne last month.

I am runing the Corsa, I have had flomaster, Borla and I love the Corsa. It has the looks, sound and quality. I had one pipe that go a little bent on the end but that was thanks to UPS. I used a rubber mallet and fixed that. It installed easily, it was harder getting the stock sys out! I love the sound, my neighbor acutally thinks that my Corsa is louder than my Borla was! But in the car it is nice sounding, not too loud, no resonace. Then when you hit it she gets a nice deep refined tone. I can't wait to hear what it sounds like when I get my long tubes. As far as gains I am not sure because I added other parts before going back to the track from my stock runs. All I know is that I can spin the F1's in 1 and 2nd by just flooring it. On the juice it is scary!
