Such a stylish motorcycle demands only the best possible exhaust system. We spent many hours in our development process to come out with this pair of titanium beauties. They are lighter, sound awesome and will save overall weight! The new Ducati 1098 / 1098S and the Akrapovic Evolution exhaust system are a fantastic combination of our years of experience at the highest level of motorcycle racing and precise handcrafting. The Akrapovic Evolution open system releases the maximum amount of power and torque, and serious riders will be able to maximize the bike?s potential on the race track. In addition to performance, the Evolution system comes in a full titanium configuration, showing a clean racing look. Of course there is also a much more powerful sound coming out of the two underseat mufflers. You will also save 3.79 kg compared to the stock Ducati exhaust system. The system is for race and track days only and is not homologated for road use. PERFORMANCE Measurements of the Akrapovic EVOLUTION system on the DUCATI 1098 /1098S without muffler insert: Power & Torque: the Akrapovic Evolution open system greatly increases the potential of the big twin cylinder engine. Both power and torque are increased over the entire rpm range, with the greatest increase shown in the middle and top of the range. We measured an incredible 154.4 hp at 9800 rpm, while the max. increased power of 8.5 hp was measured at 10380 rpm.
