TOMEI Expreme Krümmer Mitsubishi 4G63T Evo 4-9

Holding the same quality as our other Expreme exhaust components, this 4G63 EVO exhaust manifold is a perfect balance of ingenuity and is more efficient through numerous R & D testing. In the early stages of development, we worked with the original exhaust manifold to find the true limits of the factory production piece. After gathering numerous data from the original equipment tests, we slowly pieced together our Expreme exhaust manifold.

■ Made from the lost wax method.

Initial development investments were required, but the final product quality has paid off substantially. Numerous installations have been made in Japan and never once did the user experience and installation troubles or mounting difficulties. The engine exhaust port and exhaust manifold flanges have been enlarged ever so slightly to allow for a stronger mounting point, yet promote a perfect seal. And lastly, the manifold and turbo flanges is also enlarged to promote a more effective seal.

■ Additional sealing bolt is included for AT Wagon cars.

With the addition of this extra bolt it will be possible to install our product on AT transmission cars.
