This product is constructed from high-grade titanium with a sandblasted finish. Two valves with housings made in the in-house foundry tailor the sound, providing a smooth rich tone at lower speeds, rising to a true sporty sound at higher revs. The tailpipe diameter is larger than standard stock tailpipes, with a coated outer and a cast inner shell without coating – which will react with heat to take on an attractive blue colour. Each tailpipe has a laser-engraved Akrapovic logo. Power and torque are increased by 5.6 kW (7.6 hp) at 4,950 rpm and 19.3 Nm at 2,250 rpm when tested on The Akrapovic dyno against a Porsche 718 Cayman GT4 RS with a standard stock exhaust. Weight is reduced by 7.6 kg (44,4%) over the stock system. This track-oriented exhaust needs no remapping and has been developed for use on closed-course competition circuits only. Further upgrades to The Akrapovic Slip-On Race Line (Titanium) can be obtained with the addition of the optional Link Pipe Set (Titanium) and Evolution Header Set (Titanium) to create a full Akrapovic titanium system. The optional hand-made Rear Carbon Fibre Diffuser in matte or high gloss is also available to complete the ensemble.This product fits on OPF and NON-OPF vehicles.THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
