Best pricing on header, muffler and Dynojet Power Commander

I'm ready to take the plunge and do the performance mods most often recommended - header/muffler/power commander/auto tune/air box mods/ais removal/exup eliminator. I've got two WRR's to do this to.

I've seen the pipe combo on ebay at a discounted price ($520 or so) - is anybody doing a package deal for less? Package deal with the Dynojet goods as well?

Any leads to good deals on this stuff are much appreciated, thanks!
