Milltek Sport is known worldwide as one of the leading manufacturers of high-performance exhaust systems. Designed for the G8X generation BMW M3 & M4, the Axle Back exhaust system takes the car's sound and appearance to a new level — while maintaining the perfect fit and quality that the discerning M customer expects.

Designed as a direct replacement for the original rear section , this system allows the car owner to choose the exact sound signature they desire, from a quiet everyday drive to an aggressive, sporty growl. Milltek offers a variety of configurations and exhaust options to complement the already impressive look.

Improved and finely tuned sound

  • Gives the S58 engine a deeper, richer and sportier tone.

  • Maintains legality and compatibility of OPF/GPF filters.

  • The sound varies depending on the driving mode, which maintains OEM usability but adds an extra boost for sporty driving.

Installs directly without modifications

  • Complete bolt-on installation to the car's original mounting points.

  • No need for changes to the car's control unit at the Axle Back level.

Premium construction: 304L “Aircraft Grade” stainless steel

  • The same material used in the aerospace industry.

  • Excellent corrosion resistance, long service life and top-class heat resistance.

  • Welds and joints made to motorsport-level requirements.

Multiple output options

  • Outlets available in different finishes (e.g. polished, black, titanium, carbon).

  • The ability to fine-tune the car's personality to suit your own taste.
