Someone puleeese start this wittle discussion again! I learned and had fun at the same time! An aside... I know a guy with a bike dyno named Jerry Kazinski of Jerry's triumph fame [i probably spelled it wrong] who also builds tests and tunes drag bikes. Jerry also says that no slip ons make more power on most bikes. Not all slip ons on all bikes! Just most. The factories spend millions on this stuff. Sean is right on. But keep arguing! It's so fun to read!
