Honda Rebel 250 with Loud Jardine Slash Cut Exhaust Pipes Idling and Giving Her the Goose

Honda Rebel 250 start up and revving her little engine. Much louder through the first 34 gears, buzzes like a banshee at 5th on the highway. Idle is slightly louder, kinda like a 250 baby sportster if there were such a thing. This is my first working bike, planning to move up to a Phantom or Iron 883 next
