Okay guys I have a 2009 lancer es, and I put a axle-back injen ses exhaust, it sounds pretty okay, imo, but then my friend comes along and shows me his injen ses catback exhaust, and I was like 0.0 wow, so question can I turn my axle to a full cat, I know they say just weld the exhaust to one pipe, and what not, I need more clear definition, and where can I find these pipes that they talk about


thanks for the help
