Review on Boost Monkey® Ultimate Hardware Install Gaskets by Matt Dyen

Terrible! I took these because they were cheap. 1 trip and the left downpipe leaking exhaust. So I replaced it with an FCP Euro Gasket and right after that the right hand downpipe started leaking! Then I had to order another gasket. It's my fault for buying them, but here's your warning, this is by no means a temporary fix. buy fcp euro seals!
