Bought for my R1. It was as loud as it could be without it, plus you could hear the trumpet sound from the hollowed out voodoo whistle. It took care of all of that. Since this item is so cheap, it is absolutely worth the money. I haven't put my bike on a dyno, but the front wheel still goes up as it always does after installation, as does the voodoo pipe. I don't have an odometer, but I've driven it several thousand miles with no problems.
