Enhance the performance and acoustics of your vehicle with the Invidia Gemini/R400 cat-back exhaust system. Specifically engineered for the 2011-2014 Subaru WRX and STI sedan, this system utilizes mandrel-bent stainless steel piping to maximize exhaust flow and reduce backpressure compared to the restrictive factory setup. The R400 series is tuned to provide a deep, resonant exhaust note that remains manageable during daily driving while delivering an aggressive tone under load.

The system features a signature quad-exit layout finished with single-layer titanium tips, providing a high-performance aesthetic and excellent heat resistance. Designed as a direct bolt-on upgrade, it utilizes factory mounting points for a secure fit without required modifications.
