purchase a used stock xpipe without the primary cats and weld either a Turner test pipe or have a shop custom a piece for you. The stock xpipe will retain the secondary cats which help with the exhaust smell and there is no difference in power when compared to an aftermarket piece that cost $1000+. You will still save some dollars. Some just buy parts because they have the money to burn, I would rather save mine $$$$$
just my 2cents
