We need exhaust on these bikes. Shoot no wonder my neighbors complain and here me coming from 3-miles away. I guess I should stop running with just the header pipes. Aw man just kidding . Actually I run the Cobra 2" Drag Pipes with no baffles. They are very loud . If you do not like them to loud you can leave the full baffles in them and they sound nice. If you want pretty loud then cut them in half. If you want loud then cut them down to 3". I ran all three ways for awhile but for the past year I have been running no baffles. I did change jets after I drilled the stock airbox (poormans BAK) and put in a K&N Filter. Hey you could always go stage-1 through stage-3 trying out the sound after each one. Only downfall is your stock pipes are then history and you will not have nothing too fall back on if you get a fix it ticket.Take Care and God Bless Ride Safe Brother OSO
