Akrapovic Exhaust System for Porsche 911 Carrera S/4/4S/GTS (991)
Primary Components:
Akrapovic Slip-On Line (Titanium) for Porsche Carrera /S/4/4S/GTS (991) (S-PO991SO-HT/1)
It's a challenge to develop an aftermarket exhaust for the great 911. The Akrapovic engineers have prepared a superb system with a dual nature. By using the optional Akrapovic sound kit, the driver can fully control the exhaust valves, which are controlled by the car’s electronics if no optional part is used. When the valves are closed, the 911 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 Slip-On is made of special heat-resistant durable titanium alloy, with computer-designed premufflers, main mufflers, and pipes to deliver more power, more torque, weight reduction, and improved throttle response.
Fitment notice: For 911 Carrera 3.4 liter models (Carrera and Carrera 4) our system is designed to replace Porsche sport exhaust system. Akrapovic system does not fit on Carrera and Carrera 4 with Porsche non-sport exhaust system.

Optional Components:
Akrapovic Sound Kit for Porsche 991 Carrera S/4/4S (P-HF874)
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. With the use of a receiver to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller or the new smartphone app (for iOS and Android) to regulate the valves.
