So i bought an HKS hi power exhaust used and i didnt get the gasket the connects the h-pipe to the mid pipes. to better explain its the set of flanges that are the closest together. it looks like it could be one gasket. anyone know where i can get these? i called hks tech line but it sucks and never answers. i called aam and they didnt call me back. are they online somewhere? thanks for the help.
