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 most exhaust gaskets is that even if they're multi-layer, they're not completely constructed of Stainless Steel which leads to leaks. Well GrimmSpeed™ has your answer, a premium multi-layer steel w/stainless steel fire-ring gasket.
