Exhaust Header Set GM Trk/SUV 5.0L/5.7L 96-99

The BBK Performance Exhaust Header Set for GM Truck/SUV 5.0L/5.7L 96-99 is a shorty-style header designed specifically for GM full-size trucks and sport utility vehicles from the 1996–1999 model years equipped with small-block Chevy engines. This header set addresses a critical bottleneck in stock exhaust manifold design, where restrictive factory castings limit exhaust scavenging and suppress horsepower potential. Mechanics and enthusiasts choose performance headers to unlock naturally aspirated power gains while improving engine efficiency and thermal management.

Built from mandrel-bent steel tubing with a titanium ceramic coating, the BBK 4007 features 1.625-inch primary tubes that step up to a 3-inch collector, optimizing scavenging pulses across the RPM band. The shorty design maintains ground clearance and sensor compatibility while eliminating the bulky factory manifold. Titanium ceramic coating reduces underhood temperatures, protects the header from corrosion, and extends durability in harsh driving conditions. The set includes all necessary gaskets and hardware for a complete bolt-on installation, weighing just 24 pounds per pair—a significant reduction compared to cast-iron factory units that easily exceed 40 pounds.

Off-road enthusiasts, street truck builders, and weekend warriors benefit most from this header upgrade on 1996–1999 GM full-size platforms like the C/K pickup and Tahoe/Yukon lineup. Installation pairs well with intake manifold upgrades, carburetors, or fuel injection tuning for cumulative power builds. The shorty configuration clears most transmission crossmembers and suspension components without requiring chassis modifications, making it ideal for vehicles running stock or mildly modified suspensions. Verify your specific engine displacement and model year against the 5.0L/5.7L specification before purchase to ensure proper fitment.
