Product description
Upgrade your BMW G8X M3 or M4 with the Project Gamma R-Type Single Exit Catback Exhaust System, engineered to deliver an aggressive tone, lightweight performance, and a unique motorsport-inspired appearance.
Designed specifically for the S58 platform, this exhaust system replaces the factory rear exhaust setup with a straight, efficient single-exit design that helps bring out a deeper, cleaner, and more refined sound. The R-Type layout is built to reduce unwanted rasp while enhancing the raw, throaty character that the BMW G8X M3/M4 deserves.
Featuring a single 3.5-inch exhaust route, the system is designed for improved exhaust flow, reduced weight, and a bold driver-side exit with a distinctive angled tip. Whether you are looking for a more aggressive street presence or a track-inspired look, the Project Gamma R-Type Catback Exhaust delivers the perfect balance of performance, sound, and style.
