You'll have to hunt for a direct fit exhaust replacement.
If you don't mind doing some fabrication (rear exhaust / muffler mount) and maybe some clearance trimming of the right side panel, just about any exhaust sold to fit the early Hammer (1st generation engine) or 92/5 Freedom engines up to '05 or so should work. (V92C to '04, Vegas [I think] to '05)
Right side peg & brake lever / master cylinder assemblies may need spacing out, as well - depends on the system you choose.
'99 V92C with K&N, PMRT chip, Vic stage 1 slipons, and engine by Rylan Vos!
