GrimmSpeed Downpipe to Catback 3" Gasket - 02-18 WRX/STi
2002-2018 Subaru WRX
2004-2018 Subaru STi
Most aftermarket Subaru exhaust systems need a 3" 2 bolt gasket, however, a quality 3" 2 bolt style gasket is nearly impossible to find.
GrimmSpeed has worked with endless amounts of aftermarket gaskets, but none seem to work as well as the multi-layer steel OEM style gaskets. The issue with the OEM gaskets from Subaru is that they are so expensive. Well, Grimmspeed has your answer, a premium multi-layer steel w/ stainless steel fire-ring gasket at a great price!
