Sound, design and performance have combined to create this extraordinary exhaust. Akrapovic sound engineers have produced a rich, harmonic, high-frequency sound in the high-rpm range, which combines perfectly with the deep sound in the low-rpm range to provide an acoustic experience without resonances and with a sound that persists at long after the accelerator is released. Constructed from high-grade lightweight titanium, with parts made in the in-house foundry that fit perfectly into the limited space available, the three silencers - two lateral and one central - are uniquely configured. You can choose between two different sets of round titanium tailpipes, sandblasted and coated, and available in a natural or black titanium finish. The inner side of the tailpipes features a dynamic raised surface for added aesthetic value and there is an engraved logotype. Power gains of +4.8 kW at 3,000 rpm and a torque increase of +15.8 Nm at 2,900 rpm: this is the result of the test carried out on the Akrapovic dyno, using a Porsche 718 Cayman GT4 with a stock exhaust system for comparison. This gives the system, designed exclusively for track use and not intended for road use, performance that is matched by eye-catching looks and innovative design. Optional extras are available: there is a set of titanium tailpipes for the upgrade to Slip-On Race (Titanium) and a carbon fiber diffuser, matte or glossy, can be added to emphasize the design of the tailpipes. I unload. For more control over the sound of the exhaust system, the optional Akrapovic Sound Kit is available to control the exhaust valves at any time and allow the driver to choose the preferred setting. This product does not meet emissions compliance requirements for on-road or highway use. Fitment Notice: This system is not compatible with the 718 Cayman GT4 Clubsport model.
