Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you.

For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply.

Track-focused cat-back upgrade for S58-powered M cars

Part number: 081023 1510-6

Take your G-series M to the next level with a valved rear section and centre assembly engineered for the S58. This high-flow stainless system replaces the secondary section and centre silencer to unleash a sharper, motorsport tone while reducing backpressure for improved response. It integrates with the factory valve actuators, mounts to the OE hangers and uses a robust spherical joint for a precise, rattle-free fit.

We run this setup on customer builds and the feedback is consistent: crisp tone, serious presence, superb build quality and perfect fitment. Handmade in Austria with shot-blasted stainless steel and larger diameter tubing, it is a proper upgrade for drivers who want race-car character from their G80 saloon or G82 coupé.

What’s included

  • Centre sport silencer replacement assembly with integrated valves
  • Connection tube package with spherical joint
  • GPF replacement tube for OPF-equipped vehicles or front silencer replacement tube for non-OPF cars
