Milltek Sport's Particulate Filter-back exhaust system is designed to give the G87 generation BMW M2 a new level of depth and character to its sound, without compromising the car's original OPF/GPF technology. The system replaces the section of the exhaust system after the particulate filter, freeing up the S58 engine's expression with a cleaner, more powerful sound that emphasizes the car's identity.

This exhaust system offers a balance between comfort and aggression: calm city driving remains pleasant, but when you open the throttle, the M2 comes to life in a completely new way.

Improved, controlled and clearer soundscape

The PPF/GPF-back system has a strong impact on the sound of the car without interfering with the emissions system. The end result is an exhaust system that produces a deeper and more powerful tone, but without the annoying resonance or noise that could hinder daily driving.

The flow geometry designed by Milltek ensures that the sound is clean, dynamic and truly sporty — just like you would expect from an S58 engine.

Easy bolt-on installation

The system is designed to fit directly into the car's original mounting points. Installation requires no modifications to the car's structure or controls, making this upgrade straightforward and compatible for everyday use.

Made of 304L grade stainless steel

Milltek uses 304L Aircraft Grade stainless steel in its products, which is known for its longevity, corrosion resistance and excellent heat resistance. The welds and finish meet motorsport standards, which guarantees the quality of the product and its durability even in harsh conditions.

Wide range of output options

As with other Milltek systems, this package comes with a range of premium exhaust options, allowing owners to choose the look that best complements their car’s style – from polished steel to dark finishes and carbon fiber options.
