I just recently bought a em1. it came with no header, catalytic convertor, and catback system. Well basically it didn't have the full exhaust system. I was just wondering could I put my 1998 integra header, catalytic convertor, and catback system on my em1 and would it fit or no? I tried searching the whole day and only got the answer for after the em1 catalytic convertor with a integra catback system. I am planning to see if it would fit this weekend. the integra exhaust system is still bolted on to the car so I just want to see if anyone have a answer before I take it off and bolt it onto my em1 just to find out it wont work.
