MAC O/R H-pipe issue

Caboose302 · May 6, 2015

Is anyone running a MAC h-pipe? I just installed mine and is seems to move my catback forward about two inches. Now my pipes are rubbing on the frame rail and upper control arms and just barely clearing the tires.

You can see on the rear hangar how stretched it is.

By chance did you buy your cat back used? I'm asking because Fox bodies have a slightly shorter exhaust than our SN95's and will cause this.

They came on the car so I'm not sure. I hadn't thought of that. Is there any way to check other than measuring?

Did the h-pipe's hangers line up with the oem hangers? Easiest way to remedy the situation is to have an exhaust shop make you some longer intermediate/flow tubes that fit between the h-pipe and the mufflers.

No they didn't. I have a cobra catback in the garage I'm polishing up right now so I may just cut the tail pipes off and just swap it out. Just have to figure out how to hang the tails on the new exhaust first. I was wanting to finish the cobra pipes but I don't know how much longer I can put up with this be rattle.
