F20 / F21 M135 / M135i N55 Valved Catback Exhaust (2013–2016)

Upgrade the sound and performance character of your BMW with the Valved Catback Exhaust System for the F20 / F21 M135 and M135i, engineered specifically for the N55 engine. This system enhances the driving experience with a deeper, more aggressive exhaust note while maintaining comfort for everyday use.

The integrated valve control system allows you to adjust the exhaust tone depending on driving conditions. With the valves closed, the system produces a refined and balanced sound suitable for daily driving. Open the valves, and the exhaust delivers a louder, sportier tone with increased presence under acceleration.

As a full catback system, this setup replaces the exhaust from the midpipe back, improving exhaust flow and amplifying the natural sound of the N55 engine. Manufactured from high-quality materials for durability and heat resistance, the system is designed for OEM-style integration and clean installation.
