Akrapovic Honda CBR 1000 Slip-On Exhaust 2006 - 2007. The Akrapovic SLIP-ON with HEXOGONAL muffler. Exhaust system is intended for riders who don?t require extreme performance, and don?t want to make any major modifications to their stock exhaust configuration. The Akrapovic SLIP-ON system offers great looks and the renown of the Akrapovic name.  Measurements of the Akrapovic SLIP-ON system on the HONDA CBR 1000 RR (without noise damper):  Power: the system doesn?t offer a huge increase in power. If that?s what you?re looking for, check out our RACING and EVOLUTION complete exhaust systems. However, despite being just a first-level tuning component, the SLIP-ON does deliver increased power, which extends over the entire rpm range. At 11600 rpm the Honda receives 152.2 HP. Torque: the torque gains are similar to the power curve. A slightly better result is obtained in the middle of the range at around 5000 rpm. The Akrapovic Slip-on line represents the first step in exhaust system tuning. It is simple to install and replaces a stock muffler. It is also the best compromise between price and performance. With our Slip-on system you will get more power, more torque and less weight, which all reflects in a smoother ride.      * A carbon fiber outer muffler sleeve is also available     * The muffler clamp is made from carbon fiber; the metal clamp that is welded to the muffler can in some cases replace our regular carbon fiber clamp
