Description
Enhance the power and sound of your Chevy or GMC truck with the Stainless Works Headers with High-Flow Cats, engineered for the 2014-2018 Silverado and Sierra 1500 models. These high-performance long tube headers are designed for maximum exhaust flow and horsepower gains, making them a perfect upgrade for serious enthusiasts. Featuring 1-7/8” diameter primaries and 3” collectors, this system is optimized for both 5.3L and 6.2L engines.
Crafted from premium 304 stainless steel, these headers are built to withstand extreme conditions while resisting corrosion and fatigue. The precision TIG welding and thick 3/8” flanges ensure long-lasting durability and a leak-free seal. The integrated high-flow catalytic converters enhance performance while still offering improved emissions control compared to catless systems.
This system utilizes Stainless Works' Performance Connect design, meaning it connects directly to Stainless Works’ true dual exhaust systems for a full high-performance exhaust solution. With an X-pipe crossover design, these headers deliver smoother exhaust flow and a crisp, aggressive exhaust note that sets your truck apart.
Proudly made in the USA, Stainless Works headers are backed by a limited lifetime warranty, offering you confidence in both quality and performance.
