What it feels like

In Efficient or Comfort, the car remains civil thanks to the closed valves. Open it up and the quad 102 mm tips deliver a rich, race‑bred note with crackle and presence, without the harshness you get from inferior systems. Our own workshop has fitted many of these and customer feedback has been consistently excellent on fit, finish and sound quality.
