Description
Factory exhaust manifolds restrict airflow and kill performance on LS-powered trucks. These JBA headers increase scavenging efficiency and boost horsepower and torque across the RPM range while improving exhaust gas flow. Pair them with a quality exhaust system to unlock the full potential of your 4.8L or 5.3L engine.
