Hell, the exhaust may still fit up!
620 exhaust doesn't fit around the small case S2R swingarm because it interferes with the top swoopy bar, but I'm thinking the hyper exhaust should certainly clear a DSS swingarm.
I'd be willing to bet you could put any header/mid-pipe combo on any other 2V (obviously large to large and small to small) unless it depends on the SS or new monster frame openings. although it would look funny to have the s2r shotguns on a DSS bike (I would do this with one of the slip-fit mid-pipes so there would be some wiggle room). The only caveat is the stubby header pipes have to match the mid-pipe set up.
