[QUOTE="charismaticmegafauna, post: 618489, member: 665"] In the mid-'60s, [I][U]Cycle World[/U][/I] did an in-depth story on aftermarket exhaust (stock, megaphones, open pipes, etc) and intake modifications (air filters, no a.f., velocity stacks, etc) on a, then popular, Honda -- using C.R. Axtell's dyno. When it was all over, they showed the most power (averaged) over the widest rev. range with all the stock pieces (mufflers and air filters) in place. They did show various peak improvements in localized rev. ranges with some of the other set-ups. 'The more things change, the more they stay the same'.... :huh: :blink: Manufacturers have dynos, too.... :o :rolleyes: :) Good on ya', for your attempts and report. [/QUOTE]
