Corsa is a love/hate thing with me. Absolutely love the sound and looks of the tips, but I think the mufflers are complete junk. I had two Corsa systems at one point. One the muffler baffler came lose inside the case, and my last system, the outlet on the muffler, the weld cracked. Traded for a Borla, and haven't looked back. One thing I will say about Corsa, is they did send me a new muffler the first time. I think its a known issue with the mufflers. I also think, to drop the coin on the catback, they should fix the known issues....Good luck, just wanted to state that, so if it does ever happen to you, you should call and get a replacement. If you didn't register your system, you might want to do so, because they do ask you for that info. At least they did when I called. Search my name on youtube and you should be able to hear sound clips of my 97z with the Corsa. I will try and post a video of my 99 later on for ya.
