meh. i dont care anymore. its fitted.
catback is for s14/15, cat is for s14 (hi flow is the one with the flange that wasnt quite right), original cat was original (lul), dump and front were original and the front pipe bracket (to the box) fit perfect. first am performance pipe didnt.
im not blaming his work or questioning his knowledge, because both are awesome. but at the end of the day, new pipe fits the way the factory one did, bracket and all, old one didnt.
