SLIP-ON OPEN EXHAUST SYSTEM for the APRILIA RSV4

Our sporty and lightweight SLIP-ON systems offer a great balance between price and performance and represent the first step in the exhaust system tuning process. The change will also be visual as our HEXAGONAL muffler perfectly fit the exterior line of the RSV4 and add a clean racing image.
The muffler outer sleeve is made of titanium or carbon-fiber, which gives a special hi-tech touch to our SLIP-ON system. We offer the EC Type approval version with high flow catalytic converter and open system for race track use only.

Performance

Measurements of the Akrapovic SLIP-ON EC Type approval/OPEN system on the APRILIA RSV4 (without muffler insert):

Power & Torque: the exhaust system modification with the SLIP-ON system results in a major boost in performance, delivering a massive 167.9 HP at 12450 rpm on the back wheel. But the increased power isn’t available just at the top of the range; the system shows its quality from 4000 rpm already up through the entire rpm range. Max. increased power between the Akrapovic and the stock system is 5.2 HP at 7000 rpm. Besides this, the torque is substantially higher in a lower rpm area at 4500 rpm and from middle to high rpm area.
