A Heavy Duty Multi-Layer 2.25"/2.5" Gasket with ALL Stainless Layers and Fire-Ring?? Yup!

If you've dealt with sourcing exhaust gaskets before, you know that there are a lot of different options at a lot of different price points. Unfortunately, a gasket with stainless, multi-layer construction and gauranteed quality 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 gaskets. The issue with the most exhaust gaskets 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 stainless steel w/ stainless steel fire-ring gasket at a great price. This particular gasket is designed to fit most 2-bolt Subaru 2.5" applications. We've provided dimensions below, so that you can verify fitment prior to purchase!

  • 304 Stainless Steel Fire-Ring
  • 5x Stainless Steel Layers
  • 'Universal' 2-Bolt, 2.25-2.5" configuration


  • 2013+ Scion FR-S (used 3 times in the factory exhaust)
  • 2013+ Subaru BRZ (used 3 times in the factory exhaust)
  • The term universal is used loosely, here. Of course, we can't gaurantee fitment for every possible current and future 2.25-2.5" exhaust systems. For that reason, please use the dimensioned drawing below to verify your fitment.

super high quality flange gasket

This is a very high quality gasket made out of excellent material! My entire exhaust is 304 stainless steel, so having gaskets of the same material means that heating and cooling rates of the exhaust components are now equalized across components. This has led to the ability for the manifold studs/bolts to stay tight without constant need to get under the truck and tighten them every couple days. I installed these gaskets on a 1997 Toyota Land Cruiser FZJ80 with aftermarket exhaust. These fit perfectly on the flange face of the stock exhaust manifold (stock) to the Y-pipe/down pipe (aftermarket/custom). Very happy with my purchase from Grimmspeed!
