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.

Turbo downpipes for BMW F80 M3, F82 and F83 M4
Replace the OEM pre-catalytic converters
(catless downpipes or cat delete)

The Supersprint downpipes are built in Aisi 304 Stainless steel, TIG welded and mandrel bent. They fit perfectly without any adaptation, with O2 sensor bungs, flanges and mounting brackets all matching the OEM parts.

They are mostly responsible for the performance increase given by the Supersprint exhaust, thanks to the improved flow right after the turbos.

Because the secondary O2 sensors will read the wrong values once these components are fitted, the Check Engine Light will turn on (CEL). This issue must be addressed with O2 sensor cheaters, also known as micro-cats, or with a specific ECU tune. More information available on request.
