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.

Factory BMW sports rear section for the E9x 330i - transform the soundtrack of your straight six with an original BMW accessory that keeps refinement on the motorway and adds a deeper, richer tone when you want it. This axle-back upgrade brings that classic inline-six character, sharper response and a smart twin-polished 80 mm finish that looks right at home on the 3 Series coupe and convertible.

Important availability note: this genuine BMW Performance rear section has been discontinued by the manufacturer. If stock is unavailable, we recommend the Supersprint E92 E93 N51 N52 N53 performance silencer as a like-for-like alternative. Contact us for current lead times and pricing.
