Hey Bob,
That's great news on the rims. Post up some pictures when you get them. I am on the second group-buy list for the Vararam. I can not wait for it to ship and get here. The general consensus, from what I have seen, is that Injen or Vararam (from pre production dynos) give you the most gains performance-wise but CAI and Roto-Fab have the best looking kits. K&N's are nice but the 'Air Charger' system can lead to CELs but the 'Typhoon' kit does very well. These do not provide as much gains but still noticeable. Good luck with your decision. If you want to, here in the link for the Vararam group buy Second round.
