I have a 07 gt500. I bought the Lethal performance off road X pipe. Lethal Performance 07-09 GT500 Offroad X-Pipe (No Cats) [LP-GT500ORX] : Lethal Performance, Performance parts for Ford Mustangs and I also have Ford Racing stingers. The shop messed up the exhaust pipe going from the X pipe to the mufflers so I have to order a new one. Where can I get new pipes from my X to my mufflers?
