[QUOTE="Robot_trainer, post: 16019377, member: 157423"] Thanks beefcake! I have it narrowed down to Kooks 11422200 headers. Where im note sure is the cat system. I want to run something to keep the environment police happy. My two choices are the H pipe version hi flow cats or the green cats (11423300 for the green 11423500 hi flow). My understanding is you are more likely to thow a code on the rear 02 sensors because the high flows let more stuff through usually corrected with a tune and/or 02 restrictors. The car is not raced. Rarely sees over 5000 rpm. It comes down to what gives less grief. Any advice? [/QUOTE]
