To those running a coupe midpipe and the hks axelback muffler are you guys using the oem style metal ring gasket or are you using the more traditional style gasket? I just put on the coupe midpipe with stock muffler on my 04 sedan and i used the metal ring. But now i want to get a different muffler becasue my flange is rusted off and have a small leak. Any input is appreciated

 

I've used both in the past with no issues. My HKS is long gone though.........
