Good luck trying to find a Saleen original equipment kit. These were limited edition cars and inventory seems to have been depleted a couple of years ago. There might be replicas still being popped by the aftermarket. Try MrBodyKit - I think VIS Racing or Versus used to make these parts; there might be others. Also, remember you'll need dual tipped exhausts.
