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.

Improved flow and ride feel

Milltek Cat Back Exhaust System:

• reduces exhaust back pressure

• supports engine's sensitive throttle response

• improves the overall driving experience

The freer-flowing structure also supports moderate power upgrades.

Easy bolt-on installation

• to fit directly into the car's original mounting points

• for installation without welding or permanent changes

• compatible with rear-wheel drive (not xDrive) models

OEM-level fit ensures effortless installation and a clean finish.

304L Aircraft Grade Stainless Steel

The entire system is made of high-quality 304L grade stainless steel , which offers:

• excellent corrosion and heat resistance

• long service life

• flow-optimized structure

• carefully finished TIG welds

The choice of materials meets Milltek's high quality standards.
