Got the Cobra Speedster Slashdowns installed with the Fi2000R...I wasn't sure if I should go with baffled or unbaffled. The dealer asked me if I wanted it to sound like a Chopper...I said yes of course, so unbaffled it is. But my main concern was that people hear me. (tired of people just pulling out in front of me without looking). Anyway they look and sound great! But wholly crap they're loud. I'm still not sure if it's something in my helmet rattling or in my Head. Does any one know, if I put my baffles back in am I going to lose that nice rummble. I like the way they sound. Just don't know if my head can handle it. Thanks for any input. P.S do I have to readjust the fi2000r? I'm not much of a mechanic.
