one question. Why HFC's? why not get test pipes. you have an 03. w/ test pipes you get, better sound, better power, and no CEL. and with the invidia exhaust it would sound pretty killer IMO

Better sound - debatable at best
Better power - not by a truly meaningful level
No CEL - not always. Early cars are less prone to CEL's from test pipes vs later cars, but it can still happen
hey its ok guys, i already purchased the AAM HFC, they are pretty sick i must say, but put a hole in my wallet. I was looking at the test pipes but they wouldnt allow me to pass emissions.

A 1-3WHP difference on average between test pipes and HFCs isn't worth some of the headaches associated with TPs. The sound isn't always better, as TPs are more prone to rasp and drone.
