I purchased dougs headers & pypes exhaust with Goerlich mufflers. I bought these mufflers because they were listed as one of the best in Jim Hand's book. UNDER NO CIRCUMSTANCES CAN I RECOMMEND TO ANYONE TO BUY THE PYPES SYSTEM. I did and I regret it. I threw part of the system away because there was no way it could fit. Please take the advise of several others on this site and go to a local muffler shop and have them bend you up an exhaust system. You will be much happier. On the muffler side, the more research you do the better. The baffle type mufflers(flowmaster) sound better but do not flow as well as the straight thru design(Goerlich & Dynomax Ultra Flo). I did extensive research before I purchased my system.
