Evolution Link Pipe Set (Titanium) was tested and developed together with Slip-On Line (Titanium).This full titanium accessory features complex parts cast in Akrapovič’s in-house foundry and is constructed from lightweight high-grade alloys to reduce weight. Combining the Evolution Link pipe set (Titanium) with the Slip-On Line (Titanium) exhaust creates a system that is perfectly in tune to deliver the very best aural experience in all driving modes. Akrapovič’s sound engineers have worked hard to produce a sporty V8 sound with an unmistakable Akrapovič character, while keeping it smooth and eliminating any drone, all designed for maximum everyday comfort. The sound is closer to that of a muscle car and delivers an exhilarating soundtrack. With a cast collector on the link pipe, where the gases from both sides of the engine mix, the link pipe provides a smooth flow for the gas and aids in providing the perfect sound as an ideal upgrade for the Slip-On Line (Titanium).
