Heh heh...I'm looking for
quality noise, ya see...straight through pipes (so favoured by
those people) are so...well....
gauche.
Just my personal opinion (and not looking for validation of my decision to install Scorpions), but I think the only weak part of an FZ6's design and appearance are the plastic muffler covers; that's what put me off an FZ6 initially until I started appreciating the FZ6's superior ergo's over its competitors. Yes, I know that they run cooler to the touch, etc., but taking a passenger is not an option for me. It wouldn't have been much of a stretch for Yamaha to have come up with a more attractive alternative.
IAE, I'm installing the Scorpions for appearance as well as a modest decibel increase. I doubt very much that I'll be any more inclined to use full throttle any more than I am with the OEM mufflers.
