The first two that come to my mind:
* http://halo2.junk.ws used to be a good stat-tracking site, although it's on hiatus right now, presumably for maintenance.
* HALOader is a PHP-based application that can grab your stats from bungie.net using RSS.
HaloImpulse.com also used to be a Halo 2 stat tracking service, but it isn't anymore.
