Pick up some longer bolts for the cat, the stock ones won't work. Even if you get them on, they completely collapse the springs. You will probably also want the Cobb or Kartboy urethane ex. hangers, most Brullen exhausts will hit the diff with the soft rubber hangers.
In my experience, all CAI's will be loud at high throttle openings too... just take the plumbing off of the filter box and drive it to "see" (hear.) I'm not knocking the Ganzflow, it's a good product for the price.
