I just installed a CORSA exhaust on my new GTO. I am very happy with the fit and finish of the product. The sound is AWSOME! The car sounds like a true muscle car now with the CORSA system. The best part about the system is that it is agressive when you want it to be, and quiet when it needs to be. I will post some pictures soon as well as some sound clips. Jeff :D

Pictures will be comming today! Sound clips will be put on the forum today as well. Lingenfelter uses nothing but CORSA on his GTO'S. Look at his web sight. :D

Cool. Thank you for posting your impressions. Any "seat of the pants" feel for a power increase?

That's a future upgrade, be sure.

I love CORSA, too. And, still may put one on having just put one on my son's 2004 Silverado 5.3l. The sound is awesome with no resonance. But, while I know catbacks are not giving to give major hp gains, the CORSA on the GTO is 2-3 at the wheels per an email exhange a couple weeks back with them. The merging from true duals to single pipe reduces the amount of power they can make. I am taking a look at Borla but, still concerned about resonance. Ultimately, I may say the heck with it and just go with CORSA for fit, finish, looks and sound.

In regard to exhaust. Can someone more knowledgeable than me, which is probaby all of you, tell me about exhausts in regard to brand, type, etc.?
Is it more about preference and the sound they produce or is there a definite difference in quality between companys. I see stuff from Corsa, Borla, etc. Can anyone clear this up for me? Thanks in advance. :confused

I went ahead and bought the CORSA Sport with oval tip. I got a good price on eBay for $795 including shipping and handling. Best price was LPE at $845 plus before I found that. The exhaust does indeed sound great. While it is Y'd to a single pipe, the change to true 3" tubing, gentle bends and straight through muffler enhanced the sound, beautifully. It now sounds like it was intended to sound, IMO. The Oval tip looks classy to me. It looks like it was specifically made for the opening in the rear valance (spelling? CORSA quality, CORSA fit and finish. And, while I know that catbacks are not too problematic with warranties, it sure is nice to have the GM logo right on the CORSA box and GM approved in your paperwork!

Oh, sorry, CORSA has NO interior resonance. Their RSC design is no joke when it comes to that claim. The muffling concept of using sound wave cancellation (and why the muffler can be straight through with no stuffing or baffling to wear out, blow out, compact) is clever.

I did it myself. I have done a few cars myself and have found that it is not too difficult, even on ramps which is what I use. It took me a shade under 3 hours start to finish. Only about 30 minutes to remove the stock exhaust. The balance of the time was more than I figured simply because the top side of the Y tube which must face up was not marked and it was a 50/50 of getting it right. I did not (which is why I shy away from any kind of betting). Not a big deal, just unbolted the Y tube and reinstalled. Once that was done, the balance was less than 30 minutes. The torca clamps that CORSA uses are great. If you really seat them and tighten them, they rarely loosen much at all even after several heat and cool cycles.The GTO was actually the easiest of any I have done (C5 w/Xpipe, Jetta GLI, Mini Cooper S).
