The Akrapovic Slip-On Line system is the first step in exhaust tuning. Crafted from high-grade titanium, which considerably reduces the weight in comparison to the stock system, it has been perfectly designed to fit directly onto the existing link pipes. The system increases power, provides better throttle response, and improves torque, and also conjures up an amazing sound from the naturally-aspirated V8 engine. The Slip-On Line system has two valves. The system maintaines the valve regulation of the NPP (Performance exhaust) system and is developed to be compatible with the car’s drive mode selector, and Akrapovic engineers have developed an electronic device to drive the exhaust valves for each mode—Weather, Eco, Tour, Sport, and Track—giving the driver an even greater opportunity to enjoy the sound of the Akrapovic Slip-On Line across the whole spectrum of the car’s performance. It’s topped off by four large-diameter carbon fibre tailpipes with titanium inners, to make the Slip-On clearly recognizable as an exhaust that means business.
