BBK Performance Shorty Tuned Length Headers - Titanium Ceramic - 1-5/8 in. - 1997-2003 Ford F-150/Expedition/Excursion (5.4L) - 3518

Fits 1997-2003 Ford F-150, Expedition, and Excursion (5.4L).

BBK Performance shorty tuned-length exhaust headers are engineered as a direct-fit replacement for the restrictive factory manifolds on your Ford 5.4L truck or SUV. Each header is manufactured from 1-5/8 in. CNC mandrel-bent tubing to provide unrestricted exhaust flow, significantly increasing horsepower and torque. The tuned-length design optimizes scavenging waves for more efficient combustion, resulting in improved throttle response and fuel economy.

These headers feature heavy-duty 3/8 in. laser-cut flanges for added strength and a guaranteed leak-free seal. Robotically and precision hand-welded, every set is pressure tested to ensure long-term reliability. The titanium ceramic finish offers excellent thermal management and corrosion protection. This system is 50-state emissions legal (CARB approved) and comes complete with all required gaskets and hardware for a bolt-on installation.
