Hey Guys,

Ive had my 2003 Mach 1 for some time now. Just a few mods. I now want to add a MAC Off Road H pipe, but dont know how to go about it at all.

My exhaust is all stock except for 2 flowmaster super 44 mufflers.

Any ideas? Cats no cats? And which MAC do I buy to just bolt in?

Well how loud do you want the car? Loud? If so go w/ catless. And then get rear 02 MIL eliminators. As for swapping the midpipes it's fairly easy. The passenger side bolts where the midpipe meets the manifold can be a bitch but a few swivel sockets and extensions get the job done. I suggest shooting some PB blaster on all the nuts before you try to get them off. You won't need a gasket for the drivers side as it is a ball and socket connection but you will need a gasket for the passenger side. Don't, I repeat DON'T use the paper gasket Mac will give you. Go to Ford and get an OEM one. Other than that, have fun!
