Solution to my leaking exhaust....

ahh I see, so I can just take that out and put in a regular nut and bolt instead?

Take the studs out and go get a set of studs with the same threads without the shoulder in the middle. Autozone had a set that fit mine. Be sure to take the nuts when you looking for a set to test fit to the new studs.

You need a stud like this without the big shoulder in the middle.

I have an idea how about put your factory pipe on and ditch that aftermarket junk

The piping itself is correct. For whatever reason, some Mustang models leave the factory with a different style header stud on the Driver side, one that has a "shoulder" on it. This shoulder interferes with the flange, not allowing it to come up all the way and seal against the manifold. There are a couple of things that can be done to correct this. Both solutions require the removal of the factory-supplied studs. Once this has been accomplished, you can either A) replace them with a shoulderless-style stud, or B) simply use a nut-and-bolt setup. This should let the flange to come up further unobstructed, allowing the pipe to seal adequately on that side, providing a leak-free fit.

nice post jeff

Aftermarket junk? I got a lot more power from the O/r X pipe than I did with the heavy ass stock midpipe, plus matted with the Mags it sounds great

Did you ever get the studs put in?
