Anyone try or run one of these power spray water boxes? Are they really that much louder than the other noise makers? It couldn't be that hard to cut the end of a stocker, gut it and weld the end back on. You would just need to know where the fitting goes and the inside diameter of the fitting.

extremely loud and could result in fines for excessive noise. To order, place the letters “PS” after the
appropriate part number. Example: 02-0058-PS Kaw Ultra 15
