I bought the XFM16 kit for my 04 Mach 1. The kit went on well and was solid when complete. I also had bought 02 sensor extender cables and the Ford exhaust gasket for the passenger side exhaust manifold. Upon testing there were no leaks. The sound became louder compared to the stock H pipe which for the first time made the mach 1 sound like it should have. The cat-back portion of the system is stock Mach 1 turbo mufflers. The car is a 5 speed manual and roars well. I expect I picked up about 20 Hp. High quality product would recommend it to Mustang GT or Mach 1 owners.

Very Satisfied
