The most guaranteed leak you will get though is if you run an aftermarket 3" downpipe to an OEM or OEM like 2.5" Exhaust. Compare our adapter to the competition and you will immediatly see why we offer the best solution to finally end that pesky leak. Cut from Steel and hand welded these pieces were born tough. With the ability to work with both flat style gaskets AND donut gaskets they cannot be matched. If that wasn't enough we flared out one end to just shy of 3" so that unlike the competitors, our adapter will not block flow!  A Final solution to pesky problems, it's what you can expect from GrimmSpeed™ NOTE: GrimmSpeed 3in. Gasket and OEM Subaru Donut Gasket SOLD SEPARATELY Fitment Note: Adapter is only inteded to be used for connecting aftermarket 3in Downpipe to OEM style catback. It can not be done in reverse.
