MBRP 15-19 Subaru WRX 2.0L/STI 2.5L 3in Dual Split Rear Exit w/ 3.5in Tips - T304 (Race Version)

Dominate both the street and the track with the MBRP PRO Series 3" Race Version Cat-Back Exhaust System, built for the 2015–2019 Subaru WRX and STI. Designed for true performance enthusiasts, this system provides the most aggressive sound and unrestricted exhaust flow possible.

Constructed entirely from T304 stainless steel, the PRO Series offers the best durability and corrosion resistance in the industry. Its mandrel-bent 3-inch tubing eliminates restrictions, improving horsepower, torque, and turbo efficiency. The Race Version tuning removes mufflers and resonators for a raw, unfiltered exhaust note — delivering maximum volume and minimal restriction for peak performance.

Each MBRP system undergoes extensive dyno testing and track validation to ensure optimal flow characteristics and a perfect fit. The dual split rear exit design with 3.5-inch polished tips adds a clean, aggressive look to your WRX or STI’s rear profile.

Installation is simple and precise with a bolt-on, no-weld design that fits directly to OEM hangers using included hardware.
