With a distinctive sound as you shift through the gears, coupled with enhanced power and torque, all encapsulated in a full titanium system, the Slip-On Line (Titanium) offers the Akrapovi? experience while meeting ECE type approval. Constructed from lightweight high-grade titanium alloys and finished with two sets of carbon-fibre / titanium tailpipes, the system features complex parts crafted at the in-house titanium foundry, including the housing of the valves and collectors from the central muffler to the tailpipes. Two valves – one on each side of the muffler – tailor the gas flow to help produce that unmistakable Akrapovi? sound, which is distinctly different from the M8 with a stock system. The exhaust tone is most noticeable as you move through the gears and accelerate, and this can be further controlled through the addition of the optional Akrapovi? Sound Kit to provide increased aural pleasure. Akrapovi? has achieved power gains of 14.3 hp at 5,200 rpm and torque increases of 19.4 Nm at 5,200 rpm when tested on the Akrapovi? dyno against a BMW M8 Competition with a stock M Sport exhaust system for comparison. There is also the opportunity for further exhaust tuning through the addition of the optional Evolution Link pipe set (Titanium); using the link pipe set will change the gas flow and deliver the best sound possible from the Slip-On Line (Titanium). As a further enhancement, Akrapovi? has created optional parts to change the visual appeal of the car and accompany the beautiful finish of the system’s tailpipes. With a handmade carbon-fibre diffuser and mirror caps in matte and glossy finishes, an added special touch can be made to the visual experience.
