None of it matters other than 1/4 mile times. The Cycle World numbers in my opinion settle it for 2004 at least. Our bikes out of the box do 14s not 13.25.
Use my pipes and get a kazillion billion more horses, just send me $800.00. Vendors should have to show performance in seconds not stacked BS dyno numbers.
Example: We took a Speedmaster with stock pipes and it ran under 3 runs an average 13.8 seconds. We installed our pipes and it ran 13.4 seconds. Then you can decide if .4 seconds is worth $800.00 bucks. or 3 seconds being worth $4,000.00 bucks.
Marketers no longer make valid assertions they just sell stuff. I tend to believe Cycle World. They seem to be pretty impartial.
