Fitment Information: This gasket set fits 2002 - 2014 Subaru WRX, 2004 - 2021 Subaru STI, 2005 - 2012 Subaru Legacy GT, and 2004 - 2013 Subaru Forester XT. Features: Upgrade your exhaust system with GrimmSpeed's Exhaust Manifold to Crosspipe Gasket Set. During maintenance, replacing these gaskets guarantees efficient and reliable performance. After testing countless aftermarket gaskets, GrimmSpeed found that multi - layer steel OEM style gaskets work best. Most exhaust gaskets, including OEM ones, often leak because they're not fully made of Stainless Steel. But GrimmSpeed offers premium multi - layer steel gaskets with 304 Stainless Steel fire - rings at an affordable price. This product cross - references with Subaru part number 44022AA160. Key features include placement at the Header Collectors to Crossover location, multi - layer Stainless Steel construction, a 304 Stainless Steel Fire - Ring, being 2x thicker than the OEM gasket with 12 layers, and being sold as a pair.
Using these GrimmSpeed exhaust gaskets is easy. First, make sure your vehicle's engine is cool. Remove the old gaskets from the exhaust manifold to the crosspipe carefully. Then, place the new gaskets in the correct position, which is at the header collectors to crossover location. Ensure they fit snugly. When installing, be gentle to avoid damaging the multi - layer stainless steel construction. For maintenance, regularly check the gaskets for any signs of wear or leaks. If you notice any issues, it's best to replace them right away. Also, keep in mind that these gaskets are sold as a pair, so always use both together for optimal performance.
