More from GrimmSpeed:
“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 (including OEM) 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 stainless steel gasket with stainless steel fire-ring at a great price. We add extra layers to our gaskets to allow for more compression on the fire ring for better sealing against flanges that may not be machined perfectly flat or have warped overtime from thousands of heat cycles.
We have proven time and time again that GrimmSpeed gaskets can outlive the factory multi-layer gaskets, and often even outlive the part that they’re sealing to!”
