MBRP 15-21 Subaru WRX 2.0L/STI 2.5L/11-14 Sed 3in Cat-Back Single Rear Exit w/Carb Fiber Tips- T304

Experience the perfect balance of style, power, and sound with the MBRP PRO Series 3" Single Rear Exit Cat-Back Exhaust for your 2011–2024 Subaru WRX or STI Sedan. Designed to bring out the best in your turbocharged Subaru, this system delivers dyno-proven performance and a refined, sporty tone that stands apart from stock.

Constructed from T304 stainless steel, MBRP’s most premium and corrosion-resistant material, the PRO Series ensures a lifetime of durability and shine. The 3-inch mandrel-bent tubing reduces backpressure and improves exhaust flow—unlocking sharper throttle response, more horsepower, and a deeper, smoother tone.

The highlight of this system is its carbon fiber dual-wall tip, combining lightweight performance with a sleek, modern look. It’s perfect for drivers who want high-end styling that complements the WRX and STI’s aggressive design language.

With a bolt-on, no-weld design, this system installs easily using OEM hanger points and includes all necessary clamps and hardware. The result: a perfect fit and an unmistakable MBRP sound—bold, confident, and refined.
