h-pipe rubbing
hey guys, i put a MAC off road H-pipe on my 94 GT not too long ago. Ever since i put it on, i have been hearing a noise coming from it when accelerating. it sounds like the h-pipe is rubbing up against something else. it doesnt do this when i rev it in neutral so im assuming it has to do with the motor tilting and flexing the exhaust to rub up against something. I have looked under the car and cant find anywhere where it looks like it has been hitting. has anyone else run into a similar problem and if so, where was it rubbing? thanks.

Are your motor mounts good? sometimes when they are worn the engine can move around a little and cause your pipes to rub on the body, but may move back into normal position when you come to a stop. Also consider that different exhaust can cause a nasty resonance at certain RPM's, which is what you may think is the rubbing sound.

Check the catback for rubbing on the body above the axle where the tubes bend. Also check for rubbing on the control arms.
Check the front for the H-pipe rubbing against where the K-member bolts to the unibody. Mine was rubbing there when I used a 2.25" catco pipe. The 2.5" pipe, however, has not rubbed yet.
