The Milltek Sport Cat Back exhaust system is designed for the BMW F22 LCI M240i Coupé model, where the B58 engine is equipped with an OPF particulate filter. The factory-fitted OPF significantly reduces noise, and the Milltek Cat Back solution is developed to restore the character of the engine in a controlled and high-quality way without excessive noise or disturbing resonance.

The Cat Back system replaces the section of the exhaust system after the OPF filter, improving flow and bringing more sportiness to the driving experience while maintaining the car's daily usability.

Balanced and sporty B58 soundscape

Milltek has tuned this system specifically for OPF models:

• Deeper and fuller sound at idle

• Clearer and more dynamic sound during acceleration

• Controlled volume at cruising speeds

• No annoying drone in your daily driving

• The exhaust is ECE approved when you choose with a resonator. Without a resonator, the exhaust is not ECE approved.

The sound profile highlights the strengths of the B58 engine while maintaining premium driving comfort.
