ok, i have the dynomax exhaust and a hi-flow y with cats. the gasket at the connection between the y-pipe and the resonator pipe is gone, don't ask me where it is, i'm hoping it's not banging around in the exhaust pipes somewhere. anyway, it's a hemisphere with the middle cut out. looks like the top half of a microphone sort of, only with the center cut out. i need to know what that gasket is called and where i can get a new one because advanced and autozone have no idea since they doin't deal in aftermarket parts. any help would be greatly appreciated and the sooner the better because i basically can't drive my car until i fix it. thanks guys.
