Description
Stock exhaust manifolds restrict airflow and leave horsepower on the table. These shorty headers unlock that potential by improving scavenging efficiency and reducing backpressure—delivering measurable gains in power and throttle response. Built from stainless steel, they’re engineered to handle the demands of both street and track without corrosion or degradation.
The 1-5/8 inch primary tubes and 2-1/2 inch collector are sized specifically for the 5.3L and 6.2L platforms, ensuring optimal exhaust velocity across the RPM band. Cat4ward technology further refines flow characteristics, while the shorty design simplifies installation on trucks and SUVs with engine bay space constraints.
