Porsche 991 S / 4 / 4S / GTS

Akrapovic Slip-On exhaust porsche 991 S / 4 / 4S / GTS The Akrapovic exhaust for the Porsche 991 Carrera was a challange to develop. But the Akrapovic engineers did it again and have prepared a superb exhaust system with a dual nature. When the valves are closed, the Porsche 991 sounds deeper than stock, but not louder. When the valves are open, expect a completely opposite, pure racing sound, with adrenaline-pumping bangs. Keeping the drone effect away was one of the main tasks. The Akrapovic exhaust is made of special heat-resistant durable titanium alloy, with computer-designed premufflers, main mufflers, and pipes to deliver more power, more torque, and better responsiveness and to keep the weight down. Hard facts: plus 18 HP (at 4050 rpm) plus 35 Nm (at 4000 rpm) The package contains: – Titanium Muffler – Titanium link pipes with integrated flaps – Titanium tailpipes, – Fitting material and instructions Optional: Akrapovic Wireless kit for exhaust valves
