Mr Gasket 7161 Copper Exhaust Review

I recently tested a copper gasket for my performance car, and unfortunately, this product failed to meet my expectations. As a result of my tests, I determined that this gasket did not provide a tight seal, causing leaks in the exhaust system. While it may have been easy to install, the downsides outweigh any benefits, making it not worth the investment.

Superb gaskets. The fit was perfect and solved my problem with a leaking header. I had to redo one side because of a piece of old gasket. The gasket worked perfectly, even tightened a second time. I highly recommend them.

Used for AFR 185 heads and BBK 1 3/4 long tubes. So far, so good. The opening is slightly wider than the popular Felpro 1415 gasket. It's been about 20 heat cycles and the manifold bolts haven't loosened an iota. No noticeable leakage.
