I stopped by my dealer yesterday and asked about headers and exhuast. I want to put LT's,cats,and the rest. But I only want it to void the exhaust warranty. The service manager introduces me to his service advisor, who happens to drive a 04 GTO with mods. At first he pretty much says cat back systems are the only safe upgrade. But after a short bench racing session, he is going to see how far we can push it. For now, I'm not getting my hopes up.
