Akrapovic has constructed a complete cat-back exhaust system manufactured entirely from their proprietary titanium alloy, which introduces enhancements to the exhaust design not found in the stock system. 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.
Two exhaust tail pipe options are available; both are 100 mm in diameter. The first is made completely from titanium while the other is 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 uncompromising durability.
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 horsepower and 15 Nm/11 lbs-ft of torque are achieved. Furthermore, a weight reduction of 23 kg/51 lbs. is realized. The OEM catalysts are retained, so no reflashing of the ECU is required and the check engine light will not be triggered.
