Rinehart offers their value-minded Slimline Duals System for the rider who swaps mufflers for a different look and sound. Since the Slimlines use factory head pipe size, they mean your choices for mufflers are wide open - you can run the Slimline Duals, or switch out to many popular factory or aftermarket offerings constructed to work with factory equipment. Available in an array of finishes, Slimline Duals represent a hefty dose of value - there's a lot of pipe here for the money. Rinehart makes good power and torque without busting the budget and allows you to mix and match mufflers and head pipes.
