Well.... I got my headers Friday night at 8:30. The install was so easy I Left on a 150 mile ride at 9:00 Saturday morning. They sound AWESOME!!! I also noticed an improvement in power when pulling hard above 3500 rpm. Before I took my old pipes off I measured from the rear corner of the frame to the bottom of the pipe for ground clearance. With the old pipes I measured 3 inches. With the sandersons installed I measured 3 3/16 inches. Boyd really did a super job!!!!
