H pipe to factory cat back

[Hammer1999Gt]

Will a Mach 2.5 inch O/R H pipe connect to the factory cat back even though it isn't 2.5 inches.

Yes. Did it.

All aftermarket midpipes and catbacks made for 99-04 GT models will interchange with 03-04 Mach 1s and vice versa.

if you read about the mac h-pipe it does say on mostly all their products that they will fit any other mac AND stock pipes.

hey (give me tp) i seen you had slp with a catted H and was wondering if you had any sound clips. i have a slp cat-back and put a o/r h on for about a day,sounded terrable. also wondering how many cats your running. i wana get a mid pipe but im not wanting it to be to raspy.

Putting a 2.5" pipe on a 2.25" pipe is sort of like breathing through a straw, no?

2 high-flow cats (one each side) and it sounds good in my opinion. I don't have any sound clips though.

I have a Mac O/R X connected to the factory 2 1/4 pipes with Hooker Aero Chambers welded in. Sound clip in sig.
