The Milltek Sport Cat Back exhaust system is designed for BMW F30 328i M Sport models with an N20 2.0 Turbo engine and automatic transmission. While the factory system prioritizes comfort and noise control, Milltek's Cat Back solution improves exhaust gas flow and adds significantly more character to the engine's sound profile, all while maintaining the car's daily drivability.

The Cat Back system replaces the exhaust piping from after the catalytic converter, offering a sportier, cleaner, and more dynamic sound profile.

Sportier and Controlled N20 Sound Profile

Milltek has specifically tuned this system to complement the characteristics of the N20 engine:

• Deeper and clearer sound at idle

• More dynamic and lively tone during acceleration

• Sporty yet refined sound at high RPMs

• No annoying resonance or drone at cruising speeds

The sound profile is perfectly suited for daily driving, yet adds the desired sportiness to the 328i M Sport model.

Improved Flow and Driving Feel

The Milltek Cat Back exhaust system:

• reduces exhaust back pressure

• supports sensitive throttle response

• enhances the overall driving experience

The free-flowing design also supports moderate software upgrades.

Easy Bolt-On Installation

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

• to be installed without welding or permanent modifications

• compatible with automatic transmission and rear-wheel drive

OEM-level fitment ensures hassle-free installation and a clean finish.

304L Aircraft Grade Stainless Steel

The entire exhaust system is manufactured from high-quality 304L grade stainless steel, which offers:

• excellent corrosion and heat resistance

• long service life

• flow-optimized construction

• carefully finished TIG welds

The material selection meets Milltek's high-quality standards.
