    What ?

    Campbell X-Pipe ™ -- Patent holder; Monty Campbell invented the first X-Pipe™ exhaust long before NASCAR discovered it. He has developed over 58 different designs including the X-Pipe™ Cross-OverTM (replaces equalizer/cross-over tubes), the X-Pipe™ HeaderTM (replaces 4into1s) and the CPU X-Pipe™ (computerized, dynamically reconfigerable) exhausts. The Campbell X-Pipe™ exhaust has been demonstrated to improve fuel economy (up to 21.4%), increase horsepower (up to 40%), and decrease emissions. It has been used on motorcycles, cars, truck, boats and airplanes.


    Kind of an ad but does repeat some of what my racer bud has told me.
    What do you think ?

    Soooo.... what do you want to know?

    X-pipes can produce more power, but packaging one on a motorcycle is a challenge. There's a bit of snake oil going on here, as the power gain won't be huge. Interestingly enough, this is one of very few new exhaust systems still being offered for the XS. But besides the high price, the biggest drawback is the system isn't a direct bolt-on. A lister here bought one, and had to modify the frame/sidestand to get clearance for it and also ended up with reduced ground clearance.

      Interesting. I've seen these before but never heard them referenced to scavenging.
