Description

The Milltek Sport Cat-Back Exhaust System for the 2015-2020 Subaru WRX and WRX STI (VA chassis sedan) is built from 3-inch (76.2mm) mandrel-bent type-304 stainless steel for a freer-flowing system that reduces turbo lag, sharpens throttle response, and increases horsepower and torque with a deeper sporty tone. It finishes with quad polished GT-100 (100mm) round tips for a clean OEM-plus look. The system includes a resonated front section, connecting pipe, Y-piece assembly, and left/right rear silencer assemblies, with hangers welded in the OEM positions for a straightforward bolt-on installation using the supplied hardware.
