I have been interested in building the ripple exaust pipe. I am in the process of building a machine. It will probably be another month before Im ready, but if it works and there's enouph people interested I will sell them in a pair with 2 feet of rib with 2 inches of straight pipe on either end. Note: Im still in the process of designing and building so if there's any questions please be patient.
