Product Description

The Stainless Works DUR11HCAT long tube header kit is a high-performance exhaust upgrade engineered for 2011-2025 Dodge Durango trucks equipped with the 5.7L HEMI V8 engine. Crafted from premium 304 stainless steel with CNC mandrel-bent 1-7/8" primary tubes and TIG welded construction, these headers dramatically improve exhaust flow over stock manifolds while adding an aggressive exhaust tone and performance gains. Integrated high-flow catalytic converters and 3" slip-fit collectors with lead pipes provide a smoother path for exhaust gases and help support emissions efficiency in compatible applications.

Designed to connect at the factory location or work with existing Stainless Works exhaust systems, the DUR11HCAT is a bolt-on solution that enhances throttle response and horsepower potential without major modifications. The high-flow cats and factory connect design simplify installation, while premium materials and craftsmanship ensure long-lasting durability for performance enthusiasts. Due to their performance-oriented nature and inclusion of high-flow cats, these headers are typically intended for race/closed-course use and may not be street legal in all areas - check your local emissions regulations before installation.
