Hey, what exhaust you suggest to fz6-N -09 ? where to buy ?
'04-09 take the same exhaust as far as I know. I have Scorpion cat back system on my '05 FZ-6. They are louder than I would prefer, but came with the bike when I bought it used. I installed Db killers, which helped some. You mostly don't hear the exhaust over 35 mph now and my wife riding behind me doesn't hear it, which is a good thing for us.
Where are you located? And what are you looking for in terms of benefits from a different exhaust? Power, sound, part of an upgrade process?
