Subaru WRX/STI/LGT/FXT/OBXT Exhaust Gasket Set by GrimmSpeed

Grimmspeed™ knows that many of you replace all of your exhaust gasket at the same time while installing aftermarket exhaust parts on your car. We've decided to offer our premium multi-layer steel w/ 304SS fire-ringed gaskets in a discounted package so you can save even more!

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, premium multi-layer steel w/ stainless steel fire-ring gaskets at a great price.


  • 22% Thicker than OEM Gaskets
  • 304 Stainless Steel Fire-Ring

Please Note: A 3" Downpipe to Catback Gasket is included for aftermarket downpipe fitment.
