Proud new owner of a Silver and Blue '04. Just traded in a '02 VTX 1800 that had V&H exhaust and Power Commander. The 1800 used to rip up my friends CBR600RR up to 80. I got tired of him cleaning me up above that. Also since the wife doesn't like to ride I figured I didn't need a cruiser anymore. Needless to say the Busa has all the torque I'm used too plus gobs of horsepower. I am still under 600 miles so I keep it below 5500 rpm. Still stronger than an Ox. It may be a year to two before I fully exploit the full potential of this beast. I would however like a stronger exhaust note. Like i said power is not the issue. What is the least expensive way to hear more sound? Can the factory exhaust be modified? I don't really want to spend the bucks right now on a 4-2-1 exhaust nor do I want to buy two new cans just for some more noise. any suggestions?
