Josh at Stillen was very helpful and offered to send a replacement y pipe with the studs, but I'm not sure I wan't to bother uninstalling and possibly needing new gaskets. Anyone else running their stillen catback without the dampeners? I know that none of the other catbacks come with provisions for them, so they can't be too important.
