Can anyone tell me what mufflers came with the Grand Sports? I bought a'94 and there's steel pipes splicing the flex and straight hoses and they're rusted and leaking. I would like it a little less loud when cruising and not upset residents on a quiet lake so I'm wanting to put mufflers in. Also, anyone figured out a good way to hold the walk through window in the open position when underway? Otherwise great slalom and barefooting so far. Thanks
