Hey there. I'm new to riding on the FZ6R and was considering installing a two brothers exhaust. I know it seems kind of a waste for a Lams bike, though I guess I;ll be stuck with this bike till full licence. However there isn't much info on the net about whether modifying the exhuast on a lams bike is legal or not. A friend of mine pointed out while riding around Sydney if drivers cant hear you coming on your bike they wont even bother look out for you. There's no problem with the FZ6R as it is.. But the louder exhaust seems more like a safety thing. Can anyone shed some light on whether its legal in NSW?
