Description
Impressive Power and Performance. Take advantage of your truck’s full potential with these Flowtech 1.62-Inch Shorty Headers; Ceramic. Built with unrestricted features, these headers deliver maximum exhaust flow that increases your truck’s power and torque. This allows you to power your truck through aggressive applications with impressive performance.
Remarkable Sound. These Flowtech Shorty Headers come with a 1.62-inch diameter primary tube that delivers unrestricted flow. This ensures a smoother exhaust exit and promotes an impressive sound each time you open the throttle.
Retain Factory Catalytic Converters. These Shorty Headers are designed to reuse the stock exhaust components of your truck, including the mid-pipe and catalytic converters. This retains your truck’s street-legal status to ensure worry-free driving in all 50 states.
Highly Durable Quality. The premium-level construction of these headers guarantees reliable performance for years. They are manufactured using industrial-grade mild steel for maximum strength. They are also mandrel-bent to guarantee unmatched smoothness and consistent tubing diameter. Finally, these headers’ 0.37-inch-thick flanges are TIG-welded and machined for precision and leak-free performance.
High-Quality Ceramic Finish. These Headers come with a high-quality silver ceramic finish. Apart from the long-lasting coat that it produces, this finish also helps reduce the heat that radiates from the headers, keeping the engine bay temperature low in intense applications.
Requires Calibration. Installing these Shorty Headers on your truck will require custom calibration for operation. This allows you to fully enjoy the full range of power that these headers are designed to provide.
CARB-Approved Design. These Shorty Headers are 50-state smog legal under CARB E.O. number D-115-16. This allows you to install them on pollution-controlled vehicles with peace of mind.
Application. These Flowtech 1.62-Inch Shorty Headers; Ceramic are designed for use on all 2002 to 2006 4.8L and 5.3L GMC Sierra 1500 models.
Technical Note. Breaking in new engines with these ceramic-coated headers will damage the coating and void the warranties. As such, it is recommended to break in new engines using the old headers.
