SLIP-ON EC Type approval EXHAUST SYSTEM for the DUCATI MONSTER S4RS (2006 - 2008), S4R (2008)

The exhaust system for the S version of this legendary bike is led slightly differently from other Monsters. Therefore we have developed an Akrapovic SLIP-ON EC Type approval system which instead of two mufflers has a single muffler on the right side, but with two inlets and two outlets. In addition to performance, the Akrapovic SLIP-ON EC Type approval system also offers aesthetic quality, with an excellent look on the naked lines of the S series. Both muffler outlets are equipped with noise dampers, so that it conforms to all noise regulations for street use.

Performance

Measurements of the Akrapovic SLIP-ON EC Type approval system on the DUCATI MONSTER S4RS (without muffler inserts):

Power & Torque: the RS responds beautifully to the exhaust system upgrade, as can be clearly seen from the power and torque curves. The major performance increase can be felt already at low revs. Around 6000 rpm the Akrapovic curves follow the stock curves, while at the top of the range the Akrapovic exhaust system again delivers major increases in power and torque. At 10000 rpm we measured a healthy 129 HP. Max. increased power of 5.8 HP was measured at the same engine speed.
