Tired of the endless searching for a 3" 2 Bolt premium gasket that doesn't blow out? Most aftermarket Subaru exhaust systems need a 3" 2 bolt gasket, however, a quality 3" 2 bolt style gasket is nearly impossible to find. Until now. At GrimmSpeed™ we have worked with endless amounts of aftermarket gaskets, none seem to work as well as the multi-layer steel OEM style gaskets. The issue with the most exhaust gaskets (including OEM) is that even if they're multi-layer, they're not completely constructed of Stainless Steel which leads to leaks. Well GrimmSpeed™ has your answer, a premium multi-layer steel w/ stainless steel fire-ring gasket at a great price.


  • 22% Thicker than OEM gaskets
  • 304 Stainless Steel Fire-Ring
  • Sold individually

Intended to work with all Subaru and EVO 2 bolt 3" exhaust systems. Consult with illustration to ensure this will fit your application
