This product was developed to be used with the Slip-On Line (Titanium) for the Harley-Davidson Pan America 1250 and is intended for use on racetracks and closed courses only. Fabricated from high-grade stainless steel, the fitting of the optional link pipe removes the stock pre-muffler, benefitting from a weight reduction of an impressive 76.5% (1.9 kg) over the stock version. When installed with the Slip-On Line (Titanium) exhaust, performance is increased by 2.7 kW (3.7 hp) at 9,000 rpm and torque is boosted by 6.8 Nm at 2,900 rpm when tested on the Akrapovic in-house dyno against a bike with a standard stock exhaust. It serves up a deep racing tone, perfectly in keeping with the V-twin engine. No remapping of the ECU is required during installation.EC/ECE type approval of the Slip-On Line (Titanium) exhaust is not valid if the optional link pipe is attached.The product is developed and tested on EU vehicle specification and does not fit on the non-EU spec models. THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
