1 7/8" Long Tube Headers

The JBA 6852S long tube headers are engineered to enhance the performance of 1999-2015 GM trucks with 5.3L and 6.0L LS engines. Constructed from durable 409 stainless steel, these headers feature 1 7/8" primary tubes designed to optimize exhaust flow. Their fitment-specific design aims for a precise installation on compatible GM truck applications. The use of 409 stainless steel provides good corrosion resistance and durability for long-term use. The larger primary tube diameter is intended to improve exhaust scavenging and overall engine efficiency, potentially leading to increased horsepower and torque. Installation may require modifications, as noted in some JBA documentation regarding Z-bars. Specifically, vehicles may require Z-Bar modification or a new JBA Z-Bar P/N 1650Z for proper fitment. It's also important to note that this product may not be legal for sale or use on vehicles in California or other states that have adopted California emissions regulations due to emissions compliance; check local regulations before purchasing.
