We understand that no matter how well you may think something seals, it just isn't always perfect. Thats why we have gone forward with our production line of GMS Subaru Exhaust gaskets made out of the number 1 material used by some of the top engine builders in the world, Pure copper.

These copper gaskets are made in the USA of only the highest quality copper, they are all heat treated and will all fit perfectly to prevent any knicks when installing that can damage lesser quality gaskets. When installed properly these will provide the best and most leak free seal guaranteed!

All Gimmick Motorsports products come with a one year factory warranty.
