GrimmSpeed™ OEM Style Gasket, better than OEM quality at an attractive price.

FINALLY you have an option for an extra thick Exhaust Manifold to Up Pipe Gasket. The most troublesome mating joint in the Subaru exhaust track is the manifold to up pipe connection. So what did we do? We more than DOUBLED the OEM thickness. In all, it is 2.5mm thick, a monster compared to the 1.2mm thick OEM!

Whether it is OEM Manifold > OEM Up Pipe, OEM Manifold > Aftermarket Up Pipe, Aftermarket Header > Aftermarket Up Pipe....they all have leaking issues at this connection. Our new gasket solves this problem. 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.

  • 100% Thicker than OEM Gaskets
  • 304 Stainless Steel Fire-Ring
