Good write up Mr. Squatch! I agree, an intake and CAT back are the way to start a nice performance Focus. The gains seem small at first but when put mods together like T/B and Intake the benifit eachother and create better gains. When I started with my car I did exactily what Mr. Squatch recommended, I started with the Intake (Volant) then moved to the CAT back (Magnaflow) then I got the FC 65mm T/B, and FC udp's, FC race header, FC Flex pipe and the Coil pack and live wires.
