If you're looking for a little more low-end grunt for your 1997-2003 F-150 pickup, swapping out the stock exhaust manifold for a performance header is the best way to start. The cast iron log manifolds that come equipped as stock on 97-03 F-150s are extremely restrictive. The porous iron casting and lack of any individual cylinder primary tube length seriously hampers exhaust performance. A tubular type aftermarket shorty header significantly alleviates the traffic jam of exhaust that occurs in the stock manifold for a noticeable gain in power and torque. Usually available in chrome, stainless steel or ceramic coated, these non-porous materials, in combination with 3/16" thick mating flanges, are significantly less susceptible to leakage and corrosion (using a quality header gasket further reduces the chance of a leak or burnout at the head). Designed as a bolt-in piece, aftermarket headers will line-up with the factory y-pipe for a hassle free installation. While in the area, replacing the stock y-pipe with one that has high flow catalytic converters is another effective and popular way to increase engine performance.
