Description
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.
