this looks like a cool site does anyone know if the 2004 Mach 1 has a h or x exhaust system on it from factory thanks looking forward to this site
Welcome to the club. Lots of info here, not sure about the 04 Mach 1 exhaust I think it's an H ??? Someone else will be along in a while and let us know for sure, as there are several owners of 04 Mach1's on the site. Once again Welcome. JTS 71 Mach1
My son has an '04. It's stock and has an "H" pipe.
Welcome to the site. H pipe is correct.
Welcome.
Great to have you with us.
It looks like our 04 owners have jumped in to answer your question.
