Headers - 96-99 GM Truck 5.0/5.7L JBA1832S

Factory exhaust manifolds restrict airflow and limit your engine's potential. These JBA headers replace restrictive factory components with mandrel-bent tubing and optimized collector design, reducing backpressure and unlocking horsepower from your Small Block Chevy. Whether you're building a street machine or refining track performance, proper exhaust scavenging is the foundation of any breathing upgrade.

The 1-1/2" primary tubes and 2-1/2" collector are engineered to match the flow characteristics of 5.0L and 5.7L GM truck engines, delivering measurable gains in mid-range torque and peak horsepower. Built from stainless steel, these headers resist corrosion and maintain structural integrity through repeated heat cycles—critical for durability in both street and performance applications.
