1-7/8" Long Tube Header Kit with Cats

The Stainless Works header kit is a high-performance exhaust solution engineered to increase power and refine the sound of the 2011-2023 Dodge Durango 5.7L. The system utilizes 1-7/8" CNC mandrel-bent primary tubes to maximize air flow efficiency, while the 3" slip-fit collectors and included high-flow catalytic converters are designed to reduce backpressure. Built to withstand rigorous use, each component is manufactured from 304 stainless steel and features full TIG welding for superior durability and structural integrity. Every kit is assembled in the USA at the company's Streetsboro, Ohio facility. This product is designated for race and competition vehicles only. It is not legal for street use on any emissions-controlled vehicle and may only be utilized on dedicated competition or pre-pollution-controlled vehicles.
