alright, i just got a b18b swap in a 5th gen hatch. i also just got my apex'i ws2. problem is, i don't have a cat right now and i'm trying to avoid welding my new pipes to a test pipe. my buddies got a highflo cat off his 96 ex. i was wonder if a cat off a 6th gen ex will fit a b series motor. if not, which year cat should i get. what would you suggest i do?
