Don't get mad at me if I'm wrong, but 99.9% sure all 750 K and F and C exhausts are the same (most importantly mounting-wise) so no worries there. I paid $150 for a used, yet absolutely cherry V&H Street Megaphone. Ran fine on stock jets. Ran better with a #75 primary main. I should add that this came off a F bike and was installed on my K. C is really just slightly different tank/seat/sides, cast wheels (but not triple disk), and possibly? slightly lower shocks.
