Description
The Megan Racing OE-RS Series Cat-Back Exhaust for the Subaru WRX STi (2008–2014) and WRX (2011–2014) 5-Door Hatchback is designed for the driver who wants to unleash the Boxer engine's potential while maintaining a refined, daily-driver-friendly acoustic profile. Following a "factory-plus" philosophy, the OE-RS series replaces the restrictive OEM system with larger-diameter piping and high-efficiency polished mufflers, delivering a deep, mellow rumble and increased power without the high-decibel drone of a race-spec exhaust.
Constructed from premium T-304 Stainless Steel, this system features massive 3" mandrel-bent piping to maximize exhaust gas velocity and improve turbo spool and throttle response. The standout feature of this model is the set of Titanium-finish tips, providing an aggressive, high-performance "burnt" look that perfectly fills the quad-exit bumper cutouts characteristic of the wide-body Subaru hatchbacks. Every system is finished to a high polish and includes all necessary hardware for a direct bolt-on installation.
