http://www.camaro5.com/forums/showthread.php?t=216206 I had Lites Muffler on N Market install my Borla Atak Catback and my x pipe on my car and they did an excellent job...but the guy who did my install no longer works there so I can't vouch for anyone elses work. I'm still waiting on my catch can to come in and when it does gonna tackle that install myself too. You may try and post here
