Looks like I was wrong about that dyno. The 394rwhp was obtained with the aforementioned mods, but it still had the stock catback. The catback on the 03 is way more restrictive than previous model years, so there's at least 10-15rwhp tied up in it, in addition to the other easy mods. Either a FR500 or Bassani catback is definately in order, then!
