AKRAPOVIC EVOLUTION FULL EXHAUST SYSTEM
DUCATI MONSTER S4R / S4RS 06-08
We have developed an Akrapovic Evolution complete exhaust system for the most powerful Monster in the range, which beautifully complements this already extremely well-equipped machine. The system is designed for riders who know the value of product quality, a major performance increase and the renown of the Akrapovic brand, and who expect the maximum from their exhaust system. We shouldn’t forget to mention the HEXAGONAL muffler, which looks especially good on the RS.
PERFORMANCE
Measurements of the Akrapovic EVOLUTION system on the DUCATI MONSTER S4RS (without muffler insert):
Power & Torque: if the RS responds well to the Akrapovic Slip-On system, the Akrapovic Evolution system is a revelation. The boost in performance is massive, as you can see from the power and torque curves, with the increase covering the entire rpm range. The improvement is felt most strongly at the low end, and in keeping with the character of an Evolution system, at the high end and at the top of the range. At 9700 rpm we measured a huge 131.4 HP. Maximum increased power was 9 HP at 8600 rpm.
