3-Inch Stainless Steel Cat-Back Exhaust

The Cobb Stainless Steel 3-Inch Cat-Back Exhaust is engineered for the 2022-2026 Subaru WRX (FA24WGT MT/CVT). Constructed from mandrel-bent 304 stainless steel, this 3-inch diameter system offers improved exhaust flow capacity, significantly larger than the factory setup. This enhanced flow reduces backpressure, allowing the turbocharger to spool more freely and reach boost targets faster. The system is designed as a matched assembly, with the mid-pipe diameter, resonator volume, and muffler packing all optimized to achieve a specific sound character. It aims to provide a more purposeful sound than the stock exhaust while minimizing highway drone. The durable stainless steel construction also resists corrosion and scaling, ensuring longevity. This cat-back exhaust is particularly beneficial for vehicles running Stage 2 and above Accessport calibrations, as it supports the increased exhaust gas volume produced at higher boost targets. By completing the full-system flow improvement, it integrates seamlessly with Cobb's performance maps. Included with the exhaust system are all necessary hangers, gaskets, clamps, and hardware for a complete installation.
