Has anyone else had a bad experience with the gaskets that are provided in the M2 Performance HKS Replica exhaust kit? According to the guy who installed my exhaust and replaced the gaskets, the ones that come with the kit are complete garbage. He said they dont have something called a fire ring...or something like that...and the gasses were just leaking out of the bottom.

Heres a picture of one of the gaskets that came with the kit

 

bringing this thread back to life. hopefully

 

One of my front one leaks and sounds like poop for <1 minute or so until the car warms up then sounds perfect and cant hear the leak.

 

i reused my stock ones, and i know many others have as well with no probs
