Product Description

The BBK 4007 Tuned Length Shorty Exhaust Headers are engineered for GM trucks and SUVs from 1996-1999 with 5.0L or 5.7L V8 engines, as well as the 1999 Cadillac Escalade. By replacing restrictive factory manifolds, these headers deliver a 35% increase in exhaust flow, resulting in 10-15 horsepower gains and improved torque.

Constructed from heavy-gauge CNC mandrel-bent steel tubing with 3/8" laser-cut flanges, the BBK 4007 headers ensure durability and leak-free performance. Their patented large bore collectors enhance exhaust scavenging, while chrome or titanium ceramic finishes provide corrosion resistance and a polished look.

Designed as a direct bolt-on upgrade, these headers install easily using factory mounting points, making them a proven performance enhancement for GM truck and SUV owners seeking more power, efficiency, and reliability.
