Overview

It features a larger pipe diameter and smoother bends to limit back pressure, reducing turbo lag and enhancing overall performance. The pipe is constructed from SUS304 stainless steel for durability.
Show original supplier description
By incorporating a larger pipe diameter and smoother mandrel bends, this center pipe effectively reduces exhaust restriction and turbulence. This design leads to improved horsepower and reduced turbo lag. The 65mm inner pipe diameter is optimized for freer exhaust gas flow. Installation hardware is included for a straightforward bolt-on process. This center pipe is specifically designed for the 2008-2014 Subaru STI Hatchback models.
