OK here's the deal. When I put the new heads/intake on my car I need to replace the gasket that goes between the H-pipe head pipe and exhaust manifold on the passenger side of the car. I've looked around for it online and the going rate is between $15-$20, which IMO is freakin' ridiculous for a damn gasket. My question is this, for those of you who might have experience with gasket materials. If I were to buy a small sheet of copper at a hardware store and cut out a pattern (I have a template) would the copper compress enough to allow a good seal? The thing about the "official" gasket is that it has a crush seal (see the picture) around where the exhaust gas moves through it, and if i were to use a sheet of copper it wouldn't have that seal, but I guess I could just double up a ring of copper around the hole and maybe that would work? I'll spend the money and get the gasket if there's no other way, but if I can get by spending only $5 or less instead I'll do that. BTW the permatex sealant won't work because it can't withstand the high temperatures of the exhaust so using that as a seal ring isn't an option. Does anyone know about this?

I just reused the old one as a temporary fix because I couldn't find a new one. When I got it together, to my surprise, No leaks. You may not be this lucky though. I'd just order the new one. I know that the next time my midpipe comes off, a new gasket's goin in. Actually, the next time my midpipe comes off Long tubes are going on. =)

Well I would reuse my old one but half of it was just gone so there was a really bad exhaust leak. I really don't know why Ford didn't just make the passenger side manifold like the driver side manifold with the ball connector so we wouldn't need a gasket at all.

i ave had the same concern just buy a new gasket and save yourself the heartache.i wound up replacing the pipes in the end any way but ford designed that for alignment purposes but didnt think when they did it.

I have the old one lying on the floor in my garage from when I changed out my midpipe a few weeks ago (yes I need to clean my garage I know)... I think it's in decent shape... let me know if you want it.
