Overview

The JBA 1850S-2JS is a set of shorty exhaust headers. These headers are CAD-designed and manufactured with 1 5/8" CNC mandrel-bent tubing for unrestricted airflow. They feature a one-piece laser-cut 3/8" flange for added strength and durability.
Show original supplier description
The JBA Cat4ward shorty headers represent a significant performance upgrade over stock exhaust manifolds. They feature robust 1.5-inch primary tubing and a 0.375-inch thick flange for durability and optimal flow. They are compatible with 4.8L and 5.3L engines from 2002-2020, as well as 6.0L and 6.2L engines from 2007-2019. Additionally, they fit the AWD 2013 Cadillac Escalade ESV models (including Platinum) equipped with the 6.2L LS engine. Included with the headers are premium-quality mounting hardware and detailed installation instructions. While JBA states all products are guaranteed to fit the intended application, it's important to ensure the vehicle has not been modified from its original configuration. Some applications may require additional modifications or specific gaskets, such as OEM 6.1 manifold gaskets for certain installations.
