I have a FMF Power Core IV on my Raptor and I was wondering if the stock gasket from yamaha is the right gasket to use. Last week the gasket blew off and went inside my silencer. I'm going to try another gasket this weekend but I want to make sure i'm using the right one.

 

Check into Cosmetic Gaskets there really nice, I had them on a shee with Fatty Pipes.
