1-7/8" Stainless Steel Long Tube Headers and Catted Y-Pipe Package

The Texas Speed & Performance 1-7/8" long tube headers and catted y-pipe package is engineered for 2014-2018 Chevrolet and GMC 5.3L trucks. Constructed from durable 304 stainless steel with full mandrel bends, this system is designed for optimal flow and longevity. The full long tube header design is intended to deliver substantial horsepower and torque gains throughout the entire RPM range. This makes it a key upgrade for direct injection GM trucks seeking enhanced pulling power or improved acceleration for drag racing. This kit includes a 3-inch 304 stainless steel y-pipe with high-flow catalytic converters. For 2016+ model years, O2 extension harnesses may be required and are available as an option. Please note that modifications may be necessary for the driver side header primary on trucks with a steering shaft coupler. Additionally, the y-pipe may require modifications for 4x4 applications. This kit is specifically designed for 5.3L engines. It is not legal for sale or use in the state of California.
