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. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. 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. We're upfront about this — please be sure of your purchase before ordering.

Turn your BMW 6 Series into a true grand tourer with a richer soundtrack and sharper response

Looking for a serious upgrade for your BMW’s rear section without compromise on refinement? This Dinan stainless steel valve-controlled system is the ultimate axle-back solution for the F12 and F13 650i, the F06 Gran Coupé 650i including xDrive, and the F06 Alpina B6. Expect crisper throttle feel, smoother flow, a deeper tone under load and calm, refined cruising with no cabin boom. Finished with stealthy black ceramic outlets in an 89 mm diameter, it delivers the look to match the performance.

Why enthusiasts choose this system

  • Beautifully engineered stainless construction for long-term durability in UK conditions
  • Vacuum actuated butterfly valve for quiet cruising and an assertive note when you open it up
  • Direct bolt-on fit that uses the original hangers for factory-like alignment
  • Noticeable weight reduction versus the stock rear box for a more responsive feel
  • Refined sound profile, no intrusive cabin resonance on the motorway
  • Black ceramic tailpipes, 89 mm diameter, for a subtle, motorsport-inspired finish
