Those ARH headers are awesome!. I have a set for my 2007. When they developed the headers for the 2011 I went over to see Nick and the boys and WOW the dyno sheet after their header install was incredible! The reason the cats don't need to be large is because they don't really get used at W.O.T. your emissions system only works when your cruising, with a tune that is required for long tube headers it will take be adapted for size and the fact its a metal instead of ceramic substrate.
