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.

Give your F06 Gran Coupé the rear-end presence it deserves. This genuine AC Schnitzer quad outlet rear section replaces the standard back box with a premium upgrade featuring four 90 mm exits in lustrous chrome, each with the iconic AC Schnitzer logo delicately etched into the tips. The result is a deeper, sportier soundtrack and a far more purposeful, motorsport-inspired look without compromising everyday drivability.
Why this upgrade

- Transforms the rear aesthetics with a true quad-tip conversion
Compatibility and required trims
