Grimmspeed Manifold to Uppipe Gasket Double Thick Most Subaru Turbo Models

A solution for the most troublesome joint in the Subaru exhaust system—the manifold-to-up pipe connection. GrimmSpeed has more than doubled the OEM thickness, producing a 2.5mm thick gasket compared to the OEM’s 1.2mm, providing a superior seal that eliminates leaks at this critical junction.

This gasket works perfectly for:

• OEM Manifold > OEM Up Pipe
• OEM Manifold > Aftermarket Up Pipe
• Aftermarket Header > Aftermarket Up Pipe

After testing countless aftermarket options, we found that even OEM-style gaskets often fail because they are not fully stainless steel, leading to leaks over time. GrimmSpeed’s solution is a premium multi-layer steel gasket with a 304 stainless steel fire-ring, delivering durability, leak-free performance, and long-term reliability.

Features

• 100% thicker than OEM gaskets for superior sealing
• 304 stainless steel fire-ring for corrosion resistance and longevity
• Premium multi-layer steel construction for maximum durability
