Check your local exhaust shops. I made the assumption no one would have a mandrel tube bender. I installed my exhaust this weekend using a summit x pipe, Thrush turbo mufflers, Flowmaster rear exit tailpipes (modified intos ide exit), and Hedmann headers s-pipes to bolt to the headers. I went to a local exhaust shops to have two tubes expanded to slip over the normal 2.5 inch pipe. On the rack was a beautiful 1969 Mach 1 with a full set of MANDREL BENT custom exhaust. He did an amazing job doing the exaust. Cost was $450. I have $325 in mine and an entire weekend of headaches making it right. Definately not worth the $125 in my opinion.
