How do you increase torque on an 2001 f150 with the triton 5.4L v8?

im just curious. ive never had this much power to the wheels before. 260 hp and 325 pounds of torque. i had a '62 galaxie with a 292 v8, it was also fast, but could wouldnt go much faster than 80 tops. anyways...... ive read about possibly catback, magnaflow or flowmaster custom exhuast systems. performance chips..... new headers... cold air intake... possibly superchargers...im just a young kid.... any suggestions?
