Power +13.4 kW at 5850 rpm Torque +21.9 Nm at 5850 rpm Evolution Link Pipe Set (SS) was tested and developed together with Slip-On Line (Titanium). Constructed from  high-grade stainless steel , this noticeably lighter-than-stock link pipe features a resonator in the middle part and removes the secondary set of catalytic converters. Available for all countries (United States excluded), the link pipe delivers a  power gain  of 13.4 kW (18.2 hp) at 5,850 rpm and  torque increases  of 21.9 Nm at 5,850 rpm when tested on the Akrapovič dyno against a BMW M2 (OPF/GPF) with a standard stock exhaust. Combined with a Slip-On Line (Titanium) delivering a  deep, rich, and sporty sound without drone , it totally embraces the pure turbocharged inline six-cylinder sound. Remapping is mandatory as the stock secondary catalytic converters are removed. This product is meant for racetrack use and closed courses only. This product fits on OPF and non-OPF vehicles. THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
