Drill Your Own
You may want to consider drilling out the mufflers that are on the bike. Often times one can end up with a nice exhaust note, leaving money in the bank and with no need to remap the EFI.
If there is a center hole in the mufflers you can remove the mufflers and punch a hole (from the back) through the plate that is usually welded there. An old tire iron, straightened and sharpened, works nicely. If that is not loud enough you can then drill 4 holes in the plate at the back of the mufflers, around the center hole. Start out with 1/4" drill bit and work up until you are happy with the exhaust note.
If you have not changed the intake from stock, you should not need to worry about remapping.
Best wishes for a long, fun safe ride.
