The Milltek Sport Cat Back exhaust system gives the BMW F87 M2 a distinctly sportier, deeper and more dynamic sound that highlights the strengths of the N55 engine. Without the restrictions of OPF/GPF filters, the Cat Back system produces a more freely breathing structure, a cleaner sound and more efficient exhaust flow across the entire rev range.

This system is perfect for the driver who wants more character to the car's sound without having to change the entire exhaust system.

Full, sporty and balanced sound

Milltek's flow design brings out the classic six-cylinder sound of the N55 engine:

• Deep bass and warm tone at idle

• Dynamic and lively midrange

• Sharper throttle response sound

• Clear, pleasant output sound at high revs

• No excessive hum or resonance at cruising speeds

The sound profile is clearly more aggressive than the standard system, but still perfectly usable for daily driving.

Easy bolt-on installation

• Installation on the car's original mounting points

• No welding or structural changes required

• Compatible with the car's original valve system (depending on equipment)

• Designed to deliver OEM-level fit and premium finish

The entire installation is straightforward and maintenance-friendly.

304L Aircraft Grade Stainless Steel

The system is manufactured from high-quality 304L stainless steel, which guarantees:

• Long service life and corrosion resistance

• Heat-resistant construction for heavy-duty use

• Flow-optimized internal geometry

• A neat, motorsport-inspired finish

Milltek only uses material grades that meet premium and aerospace industry standards.

Output options

• Polished steel

• Black ceramics

• Titanium

• Carbon fiber coating

This allows the driver to tailor the car's appearance and sound to suit their own preferences.
