    Taking off the silencer

    This has been bugging me since I've had the bike. What exactly does the can do on your bike? I hear them being called silencers, so I assume their only purpose is to silence the noise emmiting from the exhaust. If I took off the "silencer" and just left the midpipe open would that result in some kind of damage?

    I ask because I am curious to know what my bike sounds like, unaltered. I wouldn't ride around like that primarily for the reason that I often come home from work around midnight + cops probably wont like it.
    The notion should be deleted from your noggin.

    AFAIK (I'm not an expert), removing the can will result in a lower pressure on the exhaust manafold - your bike will be VERY loud, and won't perform as well. I wouldn't recommend it - the can has a big impact upon performance.

    BTW, there was a crack-down here a few weeks ago - they were out on a popular biker road, checking for bikes with illegal exhaust mods. From what I heard, they pulled ALOT of bikes off the street in one afternoon.

    I don't know if it's good, but I have personally seen a guy ride with NO MUFFLER at all. It was loud, but not as loud as I thought it would be. If you want give it a try, just make sure no %%%% goes into the headers.

    There are federally mandated noise limits for the manufacturers. They have no choice but to abide by them. If you take your can off, you may run into legal trouble.

    Right. I just want to take it off, start her up and bring her through the rpms in the driveway

    I have no intention of riding without one.

    You won't likely damage anything, but an engine's intake and exhaust are carefully balanced to allow the right fuel mixture and airflow qualities. If you open one, you need to open the other. That's why a carb rejet or an ignition remap (efi) are often needed with an exhaust upgrade. Otherwise, a lean condition results (too much air for the fuel delivered), and you'll lose low end torque and often horsepower, too.

    It might be fun, though. Personally, I think a well-tuned exhaust sounds better by far than open pipes.

    Straight pipes sound like a pre-schooler ripping ass on a hardwood chair.
