A nice set of Carbon Fibre BOS cans for a carbed 900 (note they will not fit a 750 etc) These have been on my '94 900ss and sound lovely - a little louder than stock but not excessive, just a touch more bass and a little more throaty I can't see any where that says they are road legal but at the same time they aren't marked track use only... Couple of scuffs on them but look like from being in a box for a while - no road rash though ! You need to take the brackets of your stock cans and bolt them on but even then it still won't take that long to swap these over.
These are the low slung ones and not the upsweep ones like the superlight version ( before anybody gets confused ) , but they would make a great addition to any standard 900ss.
