Sane_Man, I got a pair of WileyCo slip-ons for my wife's Duc Supersport....they're well-made, sound good, good fit & finish & hardware, and have a lifetime guarantee (stainless packing). Plus, they were VERY inexpensive compared to Ferraci, Ducati Performance, Termignoni, etc. WileyCo is big in Italy, but few people here in the States are aware of them.
