This shorty header is a perfect addition to your 2000-2003 street-driven focus. A direct replacement for your cast-iron header, it retains all emissions gear and is pending C.A.R.B. approval. Expect gains of 2-3 horsepower and 3 ft. lbs or torque on a completely stock engine. On modified engines you can bet this header will make even more power. This high-quality part is constructed of 14 gauge steel with thick 3/8" flanges. All 4 of the 1 5/8" mandrel-bent runners merge into a 2 1/2" collector for maximum flow. The header is finished in several finishes to resist corrosion and discoloration and comes with one-year warranty against defects.
