The Akrapovic Slip-On system is designed for recreational Honda CRF 450 enthusiasts. It delivers an excellent combination of quality, performance, visual enhancement, easy installation and affordability. The Akrapovic Slip-On is designed for two markets; in the US it is available with an approved spark arrester, and for the EU and other non-US markets it comes with a noise damper. PERFORMANCE Measurements of the Akrapovic SLIP-ON system on the HONDA CRF 450 R (with muffler insert): Power & Torque: Up to 5600 rpm the Akrapovic Slip-On essentially follows the stock power and torque curves. It shows its true colors above that range, where it delivers significant increases to both power and torque. Max. increased power of 2.8 HP was measured at 6600 rpm. At the top of the rpm range the Akrapovic curves again follow the stock power and torque curves. CONFIGURATION The system is composed of a flared stainless steel link pipe which is welded to the muffler. It is attached to the stock header assembly with a sleeve joint secured with a metal clamp. The muffler is the offroad design with a titanium outer sleeve, and stainless steel inlet cap, outlet cap and inner perforation. The muffler is attached to the frame using an Akrapovic carbon-fiber clamp. In the US the system is available with an approved spark arrester, and for the EU and other non-US markets it comes with a standard noise damper

Measurements of the Akrapovic EVOLUTION street legal system on the APRILIA RSV MILLE (with muffler insert): Power & Torque: the Akrapovic exhaust system increase the responsiveness of the Aprilia and fill out the power and torque curves. The increase in power and torque starts already at around 3000 rpm and leads all the way to the top of the rpm range. At 10300 rpm we measured a massive 129.1 HP on rear wheel and max. increase of power 9.4 HP at 10550 rpm. CONFIGURATION The Racing and Evolution systems differ only in the selection of tubing materials. The Racing is made of stainless steel, and the Evolution is made of titanium. Both systems have conical tubes, collectors, and a link pipe. All of the system components are attached with sleeve joints secured with silicon-shielded springs. The header tubes come with interference crossover tubes, and the systems also include a fitting for attaching a lambda sensor. The HEXAGONAL muffler is definitely the most eye- catching element of the system. It is made of a titanium inlet cap and perforated inner sleeve, while the outlet cap is made of carbon fiber. The outer sleeve is available in titanium or carbon fiber. The muffler is attached to the frame using an Akrapovic carbon fiber clamp.
