Fixing Exhaust Leak at Test Pipe and Cat Back Exhaust Flange

[HyperV6]

After many years of having an a test pipe on my car it rusted out from the inside. When removing the old test pipe the 4 bolt flange on it and the cat back exhaust was rusted too. Some of the steel on my 4 bolt flange on the cat back scaled away. After installing the new stainless test pipe, I have some good leaks between the two flanges. Any way to seal this up? I see GBody parts make a copper gasket just not sure how thick it is and if it will seal it up. Any suggestions on fixing this leak?

Thanks, Craig

If its that bad, maybe more recommendable to have a new flange welded in? Wouldn't cost much

I use a high temperature "fibre" gasket on mine. Believe it will do a better job sealing than copper for you.
