Actually any TOURING model Harley Davidson muffler will work (Road King, Road Glide, Tour Glide, Street Glide, Ultra-Limited-Classic batwing bikes). There's simple L-brackets that can be made to mount them and you'll need a 1-3/4" collared clamp. Do a quick search on the forum and you'll find schematics for different brackets or even 3/4" P-clamp mounting options.
