Yeah that's what I was assuming as well, if that's the case I would get the resonator since it makes the exhaust note much smoother, then you can just use one of your stock exhaust gaskets when you put on your new exhaust and the gasket on the non welded side of the dummy and you're golden. I got a temporary gasket form a muffler shop because i misplaced one of mine and they gave me one of those ****ty paper ones, it started leaking 2 days later so i took off the resonator to replace the gasket and the friggin thing had disintegrated.
