This cat back exhaust system is manufactured entirely from titanium. One of the most important changes is the incorporation of an X-pipe in the system. The inclusion of an X-pipe increases low to mid-range power while at the same time producing a deeper exhaust note that the original system lacks. Additionally, a pair of resonators are added to eliminate any chance of in-cabin droning. The mounting flanges are made of cast titanium from our in-house foundry and ensure a perfect, leak-free fit.
Moving to the muffler section of our system, Akrapovic have retained the dual mode exhaust flap control from the original system. This allows the vehicle to have a more civilized, but deeper than stock sound at low speed. However, at higher RPM (or when selecting the S mode on the gearshift) the muffler is bypassed, creating a deep and sporty sound much more in keeping with the personality of the car.
The included exhaust pipe tips are crafted from a carbon fiber/titanium composite. The carbon fiber version was developed on the MotoGP Safety Car, which is driven at sustained high speed, to guarantee uncompromised durability. These give the exhaust a little more of an aggressive styling.
Performance has not been left out of the design. The system dramatically reduces backpressure and is an excellent starting point for further engine tuning or turbo modifications. Even when installed on an otherwise stock vehicle a gain of 11.3 horsepower and 21.3 Nm/15.7 lbs-ft of torque are achieved. Furthermore, a weight reduction of 9.4 kg/20.8lbs is achieved. The OEM catalysts are retained, so no reflashing of the ECU is required and the check engine light will not be triggered.
