BBK Performance Shorty Tuned Length Headers - Titanium Ceramic - 1-5/8 in. - Select 1996-1999 GM (5.0L / 5.7L) #4007

Fits select 1996-1999 Cadillac, Chevrolet, and GMC trucks and SUVs including Escalade, Silverado, Tahoe, Sierra, and Yukon (5.0L / 5.7L).

BBK Performance shorty tuned length exhaust headers are engineered as a direct-fit replacement for restrictive factory OEM manifolds. Constructed from 1-5/8 in. CNC mandrel-bent tubing, these headers provide an unrestricted exhaust path that enhances scavenging waves for more efficient combustion. This improved flow results in increased horsepower, torque, and throttle response across the power band.

Built for durability in high-heat environments, these headers feature 3/8 in. laser-cut flanges to prevent warping and ensure a leak-free seal against the cylinder head. Each unit is robotically and precision hand-welded before undergoing pressure testing to guarantee long-term reliability. The titanium ceramic coating provides a durable finish that resists corrosion and helps manage under-hood temperatures.
