These BBK Performance shorty tuned Length exhaust Headers are designed and constructed as direct fit replacements for all 99-04 GM Truck and SUV 4.8L and 5.3L applications.

BBK tuned Length headers offer improved scavenging waves for better combustion, which leads to improved performance and fuel economy over stock or equal Length headers.

All headers are robotically and precision hand welded and then pressure tested to ensure years of reliability and performance in the real world.
