  • Regular price £0.00
Tax included.


This product is constructed from high-grade austenitic stainless steel and weighs just 8.09 kg, 22% lighter than stock. A unique tuned resonator has been developed for the link pipe to work with the new engine to supply a unique sound experience, producing a deep, rich, and sporty sound with no unwanted drone or streaming, perfectly aligned with a pure straight six-cylinder engine. Power is increased by 8.7 kW (11.8 hp) at 5,600 rpm and torque rises by 17.1 Nm at 4,100 rpm when tested on the Akrapovič dyno with a Slip-On Line with Link Pipe Set against a standard stock exhaust on the BMW M440i. Meant for track use only and for OPF vehicles, remapping is mandatory with this product.

Fitment notice: This product fits the BMW M340i and M440i equipped with an OPF.

THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
