Tomei Expreme Big Mouth Downpipe, 2008-2015 EVO X

After testing a variety of shapes and pipe diameters here at Tomei R&D Lab, we 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 smooth flowing design, without steps from the turbocharger. Manufactured with the lost wax process, combines both strength and beauty.
After numerous tests, the 3 inches (76.3mm) greatly increases both power and torque.
Wide mouth & 3 inch piping. Achieve large power & torque gains over OEM.
