    What is different on the 99-03 and the 04-06 customs to make it to where the exhausts will not interchange?

    Different mounting system to accomodate the fact that the new one's engine can move independantly of the frame, and also a crossover between the mufflers on the new ones, rather than too f'in close to the idle mix screw on the old ones.

    That's one of many reasons I love my V&H Straightshots on my 99 - no crossover. Sure, if I'd dyno it, I'm sure the machine could detect a small flat spot due to not taking advantage of the reversion created by the crossover, but I'm not a racer, and my ass-dyno just isn't that sensitive. But now I can get to the mixture screw without burning the **** out of my hands!
