Hey guys, just finished installing my 3/4" exhaust plates and one side has a very slight leak. This is after I removed the plates and shims and cleaned them up with a power wire brush on all sides. Reinstalled and tightened everything up and one side leaks and the other doesn't. So I wondered if others experienced this and what they did to eliminate the leak. I'll go for a drive in a bit and see if the heat expands the parts and closes off the leak as the metal expands. Any thing I might have missed? Thanks!
