GrimmSpeed OEM Style Gasket, OEM quality without the high OEM price. FINALLY you have an option for an extra thick Exhaust Manifold to Up Pipe Gasket. The most troublesome mating joint in the Subaru exhaust track is the manifold to up pipe connection. So what did we do? Well lets just say we made a gasket that is as thick as Sarah Palin's accent. More than 2x thicker than the OEM. In all, it is 2.5mm thick, a monster compared to the 1.2mm thick OEM! Whether it is OEM Manifold to OEM Up Pipe, OEM Manifold to Aftermarket Up Pipe, or Aftermarket Header to Aftermarket Up Pipe....they all have leaking issues at this connection. Our new gasket solves this problem. 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 OEM gaskets from Subaru is that they are so expense. Well Grimmspeed has your answer, a premium multi-layer steel w/ stainless steel fire-ring gasket at a great price.
Fits: 2002+ WRX/STi/LGT Subaru turbo applications.
These have always worked great for me. Reasonably priced, seals great, no reason to give it any less than 5 stars.
