High-Performance Exhaust Gasket by Mr. Gasket: Engineered Material Review

Went this route after the composite gaskets that came with my Headman Hedders blew on the first run. It was a bit of a hassle to cut the material because it doesn't bend very well without tearing. The best advice is to be careful and go slow. You need to use a sharp knife on the cutting board so you can get some power. It is best to use a hammer drill for bolt holes. I've used a lot of Permatex copper sealant and it's held up great.

The original tube burned out and was beyond repair. And there is no substitute anywhere. After much searching, I brought up this problem over lunch and my brother-in-law, Pete, agreed to make one for me out of stainless steel. a leak. Then I realized I had made a mistake by making a new stainless steel tube. The…

I have not had this material long enough to judge its actual performance. Everything seems to have healed, but with time. - I can not say. What I want to do here is give advice.

I found a very good method that works. I used an off-the-shelf electronic tool…
