This GrimmSpeed gasket is a heavy duty, multi-layer 2.25"/2.5" gasket with all-stainless layers and a raised "fire ring" at the center.
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 guaranteed quality is nearly impossible to find. Until now.
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. 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. See the second image for dimensions you can verify fitment prior to purchase.
Fits most any standard 2.25"/2.5" flat exhaust flange.
