I hear ya. all of the local guys are telling me I need a catback. I really don't want to spend that kind of money on a catback if I really don't need one. I've got Kooks LT's, comp grind 224/224 .567" @ 113 lsa, a LPE CAI on the way, Magnaflow muffs with a 2.5 tru-x-pipe. The stock cat back plumbing is still there. The car sounds amazing.94TransAmGT said:That is the most economical way to go. Factory pipes and tips are fine. With an X pipe and 14616's i live the sound and dyno'd 336 before the tune on an A4.
