Description
Notable Engine Power. Upgrade your Silverado 2500 HD’s performance and power by replacing those restrictive manifolds with these impressive Stainless Works 2-Inch Catted Long Tube Headers for Performance Connect. These headers are designed with 4-to-1 mitered merge collectors and catalytic converters for decreased turbulence and increased exhaust velocity. Furthermore, these assemblies allow your engine to push the exhaust gases out of the cylinders with more ease, providing your vehicle with improved horsepower delivery and additional torque.
Aggressive Exhaust Sound. These Catted Long Tube Headers produce an intense exhaust tone that enhances your truck’s outdoor confidence. These headers also deliver an aggressive growl that fittingly matches your tough and powerful Silverado’s stance and performance.
High-Flow Catalytic Converters. Built for optimum performance, these 2-Inch Catted Long Tube Headers are engineered to outperform the restrictive factory cats. The substrate catalytic converters increase exhaust flow capacity that allows the vehicle’s engine to breathe more efficiently. Moreover, this enhanced outflow results in significant improvement in driving performance.
Durable and Well-Designed. Stainless Works manufactures these Long Tube Headers using mandrel-bent, 304 stainless steel tubing for superior airflow. This material is specifically designed to withstand extreme temperatures and resist the corrosive attacks of exhaust gases. Additionally, these headers are fully welded, and each pipe has CNC laser-cut flanges to ensure a precise fit and a leak-free seal.
Application. These Stainless Works 2-Inch Catted Long Tube Headers for Performance Connect are designed to fit all 2020 to 2025 6.6L Gas Chevrolet Silverado 2500 HD models.
