The stock 3" exhaust is more than sufficient for your engine, you want loud? Remove your muffler and add a piece of 3" exhaust pipe and you will get a loud exhaust that will sound good. Headers, you can buy shorties for an f150 and modify to fit waste of money IMO. Contact Mike at 5Star tunning, his shift strategy's will put your trucks power to full potential.
