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.

OEM centre section with primary silencer for BMW N63 V8 xDrive models

Bring back factory smoothness, refinement and correct exhaust flow with this original BMW middle exhaust assembly with integrated central silencer. This direct-fit OE centre box and connecting pipes restore the crisp, drone-free soundtrack your N63 twin turbo V8 should have, while maintaining proper backpressure and alignment front to back. Ideal as a like-for-like replacement for tired, corroded or leaking mid pipes, this genuine unit keeps your car quiet on the motorway and refined around town without dulling the authentic BMW V8 character.

We have installed this centre section for customers and on our own vehicles. Fitment is spot on, clamp-up is straightforward and feedback on sound quality and finish has been excellent. If you are searching for a factory midpipe solution, central muffler assembly or OE resonator for your xDrive V8, this is the one to choose.

Why this OE centre section is the right choice

  • Original BMW part for exact fit and hassle-free replacement
  • Restores correct NVH control to reduce cabin boom and unwanted resonance
  • Designed to work seamlessly with stock catalytic converters and rear silencers
  • Perfect solution for MOT-friendly, factory-spec sound and drivability
  • No modification required - bolt-on installation with OEM geometry
