Show original supplier description
The Texas Speed & Performance 1-7/8" long tube header and y-pipe package is engineered for 2014 and newer Chevrolet and GMC 5.3L trucks. The full long tube design is intended to deliver substantial horsepower and torque gains across the entire RPM range, making it an ideal upgrade for increased pulling power or improved 1/4-mile ETs. This kit is specifically designed for 5.3L trucks and includes a 3-inch 304 stainless steel catted y-pipe equipped with high-flow catalytic converters. Texas Speed & Performance also offers non-catted y-pipe options for 5.3L and 6.2L trucks. It is important to note that this product is intended for closed-course competition use only and is not legal for street or highway use nationwide under the Federal Clean Air Act. Additionally, purchasing this product requires signing a Vehicle Compliance Waiver. Potential modifications may be necessary for the driver's side header primary on trucks with a steering shaft coupler, and the y-pipe may require modification for 4x4 applications.
