97-03 FORD F150 97-02 FORD EXP 4.6L 1-5/8 SHORTY HEADERS (POL SILVER CERAMIC) These BBK Performance shorty tuned Length exhaust Headers are designed and constructed as direct fit replacements for all 97-03 Ford 4.6L F150 truck And Expedition applications. Each header is manufactured with 1-5/8" CNC mandrel bent tubing that offers unrestricted exhaust flow for increased horsepower and torque over factory OEM manifolds. BBK tuned Length headers offer improved scavenging waves for better combustion, which leads to improved performance and fuel economy over stock or equal Length headers. As with all BBK Performance exhaust headers they feature a 3/8" laser cut flange for additional strength and a guaranteed leak free fit.
i've bought a number of these bbk ceramic headers for a few of my vehicles. I like the ceramic version over the chrome version for obvious reasons - definitely worth the few extra $ for the ceramic upgrade. always been pleased with bbk!
