GrimmSpeed Exhaust Manifold to Up Pipe Gasket - Subaru WRX/STI - 2X THICK
GrimmSpeed built its name solving the fitment and reliability headaches factory parts leave behind, and this gasket is a textbook example. The manifold to up pipe joint is the most common leak point in the EJ turbo exhaust track, and GrimmSpeed's answer is a 12 layer, 2.5mm thick gasket with a 304 stainless steel fire ring, more than double the thickness of the OEM part. It's designed to seal reliably on your Subaru WRX or WRX STI, whether you're running factory or aftermarket manifolds and up pipes.
This listing covers all EJ turbo Subaru applications, including WRX chassis GC8, GDA/GGA, GE8/GH8 and GV8/GR8, along with WRX STI chassis GC8, GDB, GRF, GVF and VAB. SKU GRM027001.
