The BBK 99-04 GM Truck SUV 4.8 5.3 Shorty Tuned Length Exhaust Headers are high-performance direct fit replacements designed to enhance exhaust flow and engine output. Constructed from 1-5/8 inch CNC mandrel bent tubing, these headers provide unrestricted exhaust flow that increases horsepower and torque compared to factory OEM manifolds. Featuring a 3/8 inch laser cut flange for added strength and a guaranteed leak-free fit, the headers are robotically and precision hand welded, then pressure tested to ensure durability and reliability. Available in a titanium ceramic coated finish, these headers improve scavenging waves for better combustion, resulting in enhanced performance and fuel economy over stock or equal length headers.

These headers are engineered specifically for 1999 to 2004 GM Trucks and SUVs equipped with 4.8L and 5.3L engines, offering a direct bolt-on replacement for factory manifolds. Installation includes new exhaust header gaskets, bolts, and hardware for a complete fitment solution. A key installation note requires transferring the factory OE doughnut gasket from the passenger side manifold to the BBK header to ensure proper mid-pipe sealing. Ideal for street and performance applications, these headers deliver reliable power gains while maintaining OEM fitment and ease of installation.
