Tomei Expreme Turbine Outlet & Downpipe Mitsubishi EVO X 4B11 08-12

After testing a variety of shapes and pipe diameters at the Tomei R&D Lab, they found the optimum tuning point for the best performance balance. This design will extract the full capabilities from the EVO 10 4B11 engine. The design also retains the original layout to help with the ease of installation and compatibility for other exhaust parts.

The Tomei turbine outlet pipe is a smooth flowing design, without steps from the turbocharger and is manufactured with the lost wax process, combining both strength and beauty. After numerous tests, Tomei found that the 3 inch (76.3mm) pipe diameter greatly increases both power and torque.

The O2 sensor mouting boss is an M18, which makes it easy to fit the AFR sensor and comes with a blind plug to seal the hole when not in use. Included are Supra Bands made by MIKALOR, famous for maintaining the strongest torque to secure a proper strong connection.
