This product is constructed from high-grade titanium, with integrated acoustic reflectors, designed to reflect the external sound toward the cabin and enhance the overall acoustic experience of The Akrapovic exhaust. Two integrated exhaust valves, each on one side of the muffler and operated by The Akrapovic control kit, tailor the gas flow for a rewarding sound experience. The sound has a linear flow based on the rpm and engine load, offering a smooth and harmonic tone at lower revs and rising to a distinctive V8 rumble in the mid-range before reaching a crescendo of high-frequency sporty sound when the revs rise higher.The exhaust is finished with two sets of eye-catching tailpipes featuring a titanium inner sleeve and a hand-made carbon-fibre outer sleeve. The complex parts of this Slip-On Line (Titanium), including the valve housings and the two collectors, are all cast in the company's in-house titanium foundry. The system is 11.35 kg (50.7%) lighter than the standard stock system. It offers power and torque increases of 7.6 kW (10.3 hp) and 12.6 Nm, respectively, both at 5,750 rpm, when tested on The Akrapovic dyno against a BMW XM Label with an M exhaust system. The plug-and-play installation means no remapping is required, and it comes with EC/ECE type approval. A further upgrade of the Slip-On Line (Titanium) system is available through the optional Evolution Link Pipe Set (Titanium), aimed at those who want higher performance gains. Designed for exclusive track use only, installation of the Evolution Link Pipe Set (Titanium) means that the EC/ECE type approval for the Slip-On Line (Titanium) is no longer valid. The Slip-On Line (Titanium) exhaust system is ECE type approved for cars equipped with an Otto/gasoline particulate filter.
