Phff, you don't need instructions. I made one last year at Metalwork out of tread plate. Has perforated sheet metal curled into a cone inside it with house insulation as packing. I didn't make the end caps, took some off a CBR400 muffler, but could easily have done so. Though now I don't have access to a lathe.

This photo is the best shot I have of it. http://www.kiwibiker.co.nz/forums/attachment.php?attachmentid=93120&d=1208571719
