I've always had bad luck with these damn 2 bolt japanese exhaust flanges that is between the B pipe and the muffler. I had my rear seat out today cause I was busting rattles and I heard my exhaust sounded like garbage, most likely because the flange back there is leaking again.

Anyway does anybody know anywhere I can get copper or the malleable metal style flanges? All the ones I see are either header/block gaskets or header collector gaskets that look liek this:



The flanges that we need look like this:



I think I saw Jeff92SE used ball joint flanges on all of his exhaust parts. Shed some light?

 

When I installed my Greddy cat-back a few years ago, I put Copper-Kote between the flanges (without a gasket). I have no leaks.

If you are not familiar with this stuff, it is a liquid with suspended copper particles. It's most common use is for sealing head and exhaust gaskets.
