When installing an aftermarket exhaust, proper tuning is a must.

Installing a Power Box allows you to get the most out of your aftermarket exhaust and increases throttle response. A Power Box helps cure the lean issue that is run into when installing a higher-flowing exhaust and comes pre-programmed with a middle-of-the-road setting already into it, making it easy to install and go ride.
