I just received and installed a set of BUB Straight 8 Stealth mufflers on my '02 RKC. These are one of the first sets out of these mufflers. They are basically the same as the BUB 7 Stealths except they are straight cut with the black end cap. I had the 7 Stealths on a previous bike and really liked them. These have the same great EPA compliant sound.
