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