Looking to try to improve the fit between the pipe and can on my rev. The bell on my hps can seem to be about half the size it needs to be for proper fitment of the flange gasket. Called hps, they told me that the can was made to hold the stock gasket, but I dont think so... Anyone else have this problem and know a part# for a flange gasket that will fit properly. Looks kinda ratty as it is, considering the price they charge .....
