Akrapovic´s own description:
We have constructed a complete “catalyst back” exhaust system manufactured entirely from our 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.
Moving to the muffler section of our system, we have retained the “dualmode” 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.
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 uncompromised 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/50 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.
For ultimate tuning potential, additional weight reduction, and a great racing sound, we offer stainless steel downpipes without cats. These high-flow downpipes require ECU reprogramming and are a perfect fit with the Evolution exhaust system.
This product is intended to be used only on racing vehicles on closed courses. It is not for use on roads or vehicles otherwise subject to emission control requirements. In California, this product should not be used on any vehicle that is registered or licensed for use on public roads.
When installing Akrapovic’s aftermarket optional down pipes without catalytic converters, which are developed for use on closed tracks only, remapping of the ECU is mandatory.
