The Milltek Sport Cat Back exhaust system is designed for the BMW F22 LCI M240i Coupé, combining the classic rear-wheel drive experience with a powerful B58 engine without an OPF/GPF particulate filter. Without the need for additional exhaust system damping, the Milltek Cat Back solution produces a cleaner, deeper and more sporty sound.

The Cat Back system replaces the rear section of the exhaust system and improves exhaust flow, adding character and dynamism to the driving experience.

Rich and sporty B58 sound

Milltek has tuned this system to highlight the strengths of the B58 engine:

• Deeper and warmer sound at idle

• Dynamic and lively sound during acceleration

• Clear and pleasant output sound at high revs

• No annoying resonance or drone at cruising speeds

The sound profile is clearly more aggressive than the standard system, but still well controlled in daily driving.

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

The system is designed to:

• to fit the car's original mounting points

• for installation without welding or permanent changes

• to provide OEM-level fit and finish

Installation is straightforward and maintenance-friendly.

304L Aircraft Grade Stainless Steel

Milltek uses only 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 premium quality standard.

Fit

• BMW M240i Coupe (F22 LCI)

• Only for rear-wheel drive models, not for xDrive or OPF equipped models

Engine: 3.0 Turbo (B58)
