I went to the dealer because I'm putting my stock midpipe back on. I went to the dealer to get new gasket(s) for the joint between the cat section and the axle-back. They said that the only gasket is the round one. I swear there was another gasket on there when I took it apart. I purchased a used midpipe and bought a gasket from Apex at that time. It looks more like a tradational exhaust gasket. So is the stock section held with just the round crush gasket. Or does it have the round crush gasket and a flange gasket that goes around the bolts? Thanks.
