I recently got a reinforced rear fork on my 93 that doesn't fit with the stock exhaust. I put on slip-ons which are allright but I like the stock exhaust look better. Would it be possible to take the stock exhaust and cut the middle section (cat?) out and weld things back together to create two slip-on type exhausts that look completely stock? Has anybody ever done this? Would it increase or decrease airflow? Any other considerations?
