For extreme Turbocharged and Supercharged applications, Michigan Motorsports' Inconel Exhaust valves are an excellent upgrade from standard stainless offerings to improve durability and longevity. Made from high temperature-resistant Inconel Alloy, these one-piece forgings feature chrome plated stems and hardened tips for additional durability. Swirl polishing improves flow, while full diameter (non-undercut) stems are used for ultimate strength. These valves are designed to be a direct drop-in replacement for the factory 1.55" exhaust valves on the applications listed above and below.
