Pay your Sportster the ultimate compliment with an Akrapovič Slip-On exhaust system. This classic, legendary Harley-Davidson design now comes with an aftermarket Akrapovič exhaust system that offers more power, less weight, and a unique sound and looks.  The Slip-On systems are an upgradable modular system, meaning that, if you chose to do so, you can mix and match components to achieve a custom look. Change your end caps, choose chrome or black heat shields, add a noise reduction insert. You decide. The catalytic converter is removable for markets where this is appropriate. The Slip-On features an optional valve system enabling you to adjust the sound level with a simple switch?no dirty hands!
