I just purchased a FLOWTECH Glass Pack for my car, Im under the assumption that I have to remove the stock muffler.. (OF COURSE) and apply this replacement, could I just use a clamp or does this have to be professionally installed.
Hey, I had a custom catback made for mine. (consist of a pro-bent pipe and glasspack) It sounds great and only cost me $70. I know some people so I got it cheaper, but If I were you I'd def. have it done.
