Akrapovic Exhaust System for Porsche 718 Cayman GT4 RS / Spyder RS

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.

Link pipe set (Titanium) was tested and developed together with Slip-On Race Line (Titanium) system.

Fabricated using high-grade titanium and insulated with stainless steel, the front part is cast in the in-house foundry and shaped to provide correct clearance of the stock shocks. The sport 200 cpsi catalytic converters are integrated and have extra insulation for heat protection. For non-OPF cars, a new plug is included to disable the EGT sensor. It weighs in at 4.9 kg (38.9%) less than the stock system. Installed with the Slip-On Race Line (Titanium), power gains of 19.5 kW (26.5 hp) at 4,950 rpm and torque increases of 38.1 Nm at 4,900 rpm have been recorded on the Akrapovic dyno when tested against a Porsche 718 Cayman GT4 RS with a standard stock exhaust. Due to more direct gas flow, the sound has a true racing quality with high-frequency tones. This track-oriented part has been developed for use on closed-course competition circuits only, and when installed remapping is mandatory. A further upgrade is available with the installation of the optional Evolution Header Set (Titanium).

Evolution Header Set (Titanium) was tested and developed together with Slip-On Race Line (Titanium) system.

Using race-proven solutions, this high-grade titanium header set features a special manifold runner crossover part on each side. This technological innovation is a masterpiece of engineering and enhances the performance of the complete exhaust in the mid range. Several parts are cast in the in-house foundry, including the three-in-one collectors designed for smooth gas flow. The weight is 5 kg (51.9%) less than the standard system and, when installed with the Slip-On Race Line (Titanium) and Link Pipe Set (Titanium), power and torque increase by 26 kW (35.4 hp) at 4,900 rpm and by 50.9 Nm at 4,900 rpm when tested on the Akrapovic dyno against a Porsche 718 Cayman GT4 RS with a standard stock system. It provides a true racing sound, full of character with a distinct note during gear shifts. With the installation, remapping is mandatory, and this track-oriented part and full system have been developed for use on closed-course competition circuits only.

This product fits on OPF and NON-OPF vehicles.

The optional Akrapovic Sound Kit enables owners of selected Akrapovic car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovic technology, drivers can easily switch between the quiet mode and a sportier sound.
