GrimmSpeed knows that many customers prefer to replace all of their vital exhaust gaskets at the same time while installing aftermarket exhaust components in their cars. Based on that knowledge we've decided to offer our premium multi-layer steel w/304 SS fire-ringed gaskets in a discounted package! These gaskets are 22% thicker than OEM Gaskets, made from the longest-lasting materials available and are infamous for being the best in the Subaru aftermarket parts industry!
