Larger, Optimized Flow for More Power
Lost Wax casting process for maximum durability,precision without welds.Larger in size and diameter, smooth without any steps. 
The larger curve design makes it possible for a much larger capacity. Improved efficiency through with a more linear layout.
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.
