AKR Evo Cat Back - Titanium

This product is constructed from high-grade lightweight featuring a central muffler with two pairs of striking double round handmade carbon-fibre tailpipes, which contain acoustic reflectors, designed to enhance the sound experience for both the driver and passengers. The valves on both sides of the muffler control gas flow, with housings cast in-house. The weight is 44.8% (14.6 kg) lower than the sport stock exhaust. A power gain of 4.2 kW (5.7 hp) at 5,950 rpm and torque increase of 8.0 Nm at 2,150 rpm were achieved when tested on The Akrapovic dyno against a Porsche Cayenne S E-Hybrid Coupe with a stock sport exhaust system. The harmonic and satisfying sound, perfectly matched to the engine's operation, gives the impression of a V12 engine from inside the cabin. The specially developed control kit converts The Akrapovic exhaust system from a mechanical system to a mechatronic one. The gas flow from each link pipe is driven into the muffler without unpleasant streaming or whistling, with peaks at specific frequencies dampened for cruising comfort, and the sportier and emphasized sound is fully embraced when driving more dynamically. The sound experience of the Evolution Line () system is directly linked to the car's drive with no compromise to comfort or sportiness. This product has plug-and-play installation and no requirement to remap the ECU. An optional Akrapovic Sound Kit is available, which will increase the aural pleasure of The Akrapovic Evolution Line () exhaust at lower revs and further supplement the sound as the revs rise. For mounting Akrapovic exhaust S-PO/T/2 or S-PO/T/3H on Porsche Cayenne (base V6) models without Porsche sport exhaust, additional wiring kit P-HF1621 has to be bought. This product fits on NON-OPF vehicles. THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE. Akrapovic Evolution Line Exhaust System.
