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 \u003cstrong\u003eexhaust valves\u003c\/strong\u003e, 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 \u003cstrong\u003eracing\u003c\/strong\u003e 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 \u003cstrong\u003etitanium alloy\u003c\/strong\u003e, with computer-designed premufflers, main mufflers, and pipes to deliver more power, more torque, weight reduction, and improved throttle response.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment notice: For 911 Carrera 3.4 liter models (Carrera and Carrera 4) our system is designed to replace Porsche sport exhaust system.
