honda fx650 exhaust

[ts50x0]

im gettina honda fx650 in about 2 months, deos anyone know where i can get a race exhaust coz i love the sound of a big single and you cant hardly hear the engine on this thing, also its the same engine as the honda slr and xlr i beleive, so would one for that bike fit. and will i need to upjet carb or anything and take it on the dyno or will it just fit, i want it more for the sound than the power increase by the way.
the other option is to just give it to my local dealer which is slightly bent. but i still dont know if they do one which will fit.
and i know most of you havnt even heard of this bike, but those who have hat do you think as a 33bhp bike?(39bhp standard and leaving it at 39)
