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.

Unlock the full potential of your B58-powered BMW with the Supersprint race front pipe for particulate filter models, part number 522311. Built for serious track work, this no-catalyst turbo outlet replaces the restrictive OE converter on OPF and GPF cars, giving cleaner post-turbo flow, reduced back pressure and more stable exhaust temperatures during repeated hot laps. It is a precise, bolt-on solution for F-series M140i, M240i and 340i owners who want a proven motorsport-focused upgrade that fits and lasts.

Why enthusiasts choose part 522311

  • Optimised gas velocity straight from the turbocharger helps the engine breathe on circuit
  • Improved control of exhaust temperatures under sustained load
  • Direct-fit geometry for OPF or GPF equipped B58 F-series cars
  • Pre-welded lambda boss for the OE oxygen sensor
  • Designed for ease of installation and long-term reliability
  • Track use only racing component

Vehicle applications

For OPF or GPF equipped models, typically from July 2018 onward. Please confirm your car has a petrol particulate filter before ordering.

  • BMW 1 Series F20 F21 LCI M140i
  • BMW 2 Series F22 F23 LCI M240i
  • BMW 3 Series F30 F31 LCI 340i

If your B58 vehicle does not have a particulate filter, use the Supersprint B58 race pipe specified for non-OPF cars.

Track-only notice

  • For closed-course competition use only, not for public roads
  • Removal of the catalytic converter will trigger a check engine light without appropriate engine management changes
