Inventors Needed - Need Help Spacing Exhaust

If it were me I'd loosen the header flanges a bit as well as the inlet flanges and try to shift things around to fix the problem vs. trying to make a wedge or anything else along those lines. There should be enough play to get it clear of the crossmember.

You should have two hangers if I recall correctly, one for the h-pipe and one for the muffler cat-back system. Why don't you just take the offending hanger off? Your exhaust will still stay attached and you don't get any more rubbing... If this won't work you'll have to get some uncut gasket material with two of those clamps that come with CAI kits (can pick them up from just about any hardware or automotive shop and make yourself a buffer... Wrap the uncut gasket material around the pipe until you have sufficient material to stop the noise or vibration or whatever, then clamp it down on both sides with your CAI clamps. If you want, for added protection take 2 layers of aluminum foil and one tube of high temp sealant (it's red in color) and squeeze a tiny bit on one half of the foil. Then fold it over (make sure the sealant is spread out evenly). Fold it in such a way that it makes 2 layers over the gasket material and creates an added buffer. Gasket material will wear a cut in it from the vibration and the aluminum foil and high temp sealant should prevent that. You can get the high temp sealant from autozone or advance autoparts or anything like that... it should be good to 650* or something like that.. .good luck.. let me know if it works.. just thought of this on the fly... On a side note, I've never had to buy uncut gasket material so I don't know where to get it, but I know people who have had it and they had to buy it from somewhere. I would check with the equivelant of Pep boys or something like that...

That was going to come out of my mouth next. Cut the hanger off.

I say get an h-pipe that fits better. I like having the hangers, and with good quality pipes everything fits well.
