E-approved 2-into-2 systems with headers, heat shields and mufflers. Exhausts feature an adjustable exhaust valve that allows you to tune the sound of your bike the way you like it, but still get back to what is legal. These exhausts come complete with a manual operated adjusting lever that can be placed on either the handlebar or below the tank. Electric operated adjusting motors with a key fob style remote control are available as an option. "Royal Style 90" end caps must be ordered separately.
