Product Description

The JBA 1842S-10 Shorty Headers are engineered performance upgrades for 2014-2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the 4.3L V6 engine. These Cat4ward® stainless steel headers replace restrictive cast iron manifolds with mandrel-bent 1.625" primary tubes and patented Firecone® merge collectors to unlock improved exhaust scavenging, increase low-to-mid RPM power, and reduce backpressure compared to stock manifolds.

Constructed from durable 409 stainless steel with thick machined flanges, the 1842S-10 headers are built for longevity under daily driving, towing, or light performance use. Included hardware and gaskets make installation straightforward for experienced DIYers or professional shops. Note that while 2014-2016 applications are CARB approved (EO D-57-33), later model approvals may vary by state - always check local emissions laws when installing performance exhaust components.
