It’s a challenge to develop an aftermarket exhaust for the great 911. The Akrapovič 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 pre-mufflers, main mufflers, and pipes to deliver more power, more torque, weight reduction, and improved throttle response.

The optional Akrapovič Sound Kit enables owners of selected Akrapovič car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovič 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.
Cars equipped with Akrapovič exhaust systems benefit from additional performance and increased responsiveness.
