Check out McNews Automotive or some of the other sponsors on here. It will be hard to find the stock SVT cat, unless you go to a Ford dealer/parts distributor. However, the high flow and ORP is pretty easy to find. Also, check out the buy/sell/trade forums on here. I think I picked up my ORP for like $70.
