• Mandrel formed tubing with optimised diameters for smooth gas flow and sharper throttle feel

Sound and drivability

Expect a deeper, more engaging note under load and a clean, mature tone when cruising. The balance is ideal for daily use and long journeys, giving you a proper performance soundtrack without drone.

Built to last

Precision fabricated in the UK using non magnetic T304 stainless throughout. The material resists corrosion and discolouration, so it looks as good as it sounds behind those carbon fibre finishers.

Proven on road and by owners

This is a go to upgrade for OPF GPF M4 models. We have installed and used these systems ourselves and feedback from our community is consistently positive on fitment, tone and overall quality.
