100% Thicker than OEM Gaskets!!

Our new 2X Thick 3" 2-Bolt gasket is hands down the most beefy 3" 2-Bolt gasket on the market. 12 LAYERS!

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. GrimmSpeed™ OEM Style Gasket, OEM quality without the high OEM price.

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 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.

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

ALL 3" Subaru/EVO aftermarket exhaust systems

3" gasket

I kept blowing out my exhaust gaskets at higher boost and with all the back pressure from back fires on my WRX. I installed a 3" heavy duty gasket a couple months ago and it's still holding strong. Just wish I bought another to go between the down pipe and cat back!!
