Tomei Expreme Downpipe Big Mouth – 2008-2015 Mitsubishi Evolution X
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 X 4B11 engine. The design also retains the original layout to help with the ease of installation and compatibility with other exhaust parts.
