The Milltek Sport Cat Back exhaust system is designed for the BMW F22 M235i Coupé, where the powerful and rev-sensitive N55 engine is combined with the classic rear-wheel drive feel. The factory system dampens engine noise and restricts exhaust flow, while the Milltek Cat Back solution unleashes the engine's character in a controlled but distinctly sportier way.
The Cat Back system replaces the section of the exhaust system after the catalytic converter, improving flow and bringing more dynamism and sonic character to the driving experience.
Sporty and balanced N55 sound
Milltek has tuned this system specifically to highlight the features of the N55 engine:
-
Deeper and fuller sound at idle
-
Clearer and more powerful sound during acceleration
-
Sporty yet controlled sound at high revs
-
No annoying resonance or drone at cruising speeds
The sound profile is ideal for everyday use, but adds a distinctly sporty touch to the M235i's character.
