I was trial fitting the H-pipe last night,and noticed the old style hard fiber manifold gasket they give you. Those don't give a good seal over the long haul. Some folks say they reuse the original factory "O" ring gasket,but there isn't much sealing area left with the larger 2/1/2 inch flange opening. So I will try what has worked on my header collectors,on my 85 LX. I make up a copper O ring,that will offer some seal crush and high temp sealing. Other than that looks like all will fit OK. Keep you posted.

Found a good graphite coated,steel wire renforced gasket that with a little hole modifing,worked great so far. The H-pipe fit was perfect,no leaks yet and sound with stock muffs. AWESOME!!! Almost like a pair of Flowmasters. Now to tune the chip.

I've been trying to install my MAC off-road H-pipe, but unfortunately stripped the lower pasenger side header nut in trying to do so. I'm really frustrated. Does anyone have any suggestions on getting this nut off?

See if you can get a pair of vise grips on the end of the stud, and just remove the stud. IT might be a Pain in the pooper on that side thought. A 10 MM socket or somewhere around there should work as well. Then back the stud out, and replace it with a new stud, or the studs you will have to remove from the Drivers side.

The stock gasket is fine, I have never had any leak issues.....

PS use 1/2 drive tool need the torque...

email me if you have any more questions..

Actually the nut on the lower passenger side manifold/header is stripped. I'm taking it to a mechanic today to see if he can get it off. Ford must have used high strength loc-tite on those nuts!
