Product Details
If you're rebuilding the top end of your 2002-2011 Subaru Impreza, specifically the EJ205 or EJ257 engine, a new exhaust valve is a critical component. This is a single Race Master exhaust valve from Manley Performance, designed for engines running under 8000 RPM. It's built to handle the stresses of racing applications, offering a solid option for performance builds.
Manley constructs these valves from stainless steel, which is a strong material that holds up well over time. The stems are chrome-plated and feature hard tips, adding to their wear resistance and longevity, especially important in high-heat exhaust environments. The under-head area is swirl polished to help smooth airflow, and the combustion face is fully machined. This attention to detail helps optimize how efficiently your engine breathes and burns fuel.
This particular valve is a Race Master, meaning it has a straight stem. Manley also offers a Race Flo shape if your engine build requires something different. For those running alcohol-based fuels, these stainless steel exhaust valves are specifically recommended for reliable performance.
