Description
More Horsepower And Torque. Are you looking to improve the power and performance of your 5.3L V8 GMC Sierra? If so, then consider Stainless Works' Factory Connect 1-7/8-inch Catted Long Tube Headers with Y-Pipe. Stainless Works engineered their Long Tube Headers, High Flow Cats and Y-Pipe to all work together to improve the exhaust flow of your V8 Sierra. By uncorking your Sierra's restrictive factory exhaust system you will see a dramatic increase in horse power and torque throughout the entire RPM range. This Stainless Works' Factory Connect system is designed to bolt up directly your Sierra's existing stock Cat-Back exhaust, so there are no extra parts to buy.
High Flow Catalytic Converters. Stainless Work's high flowing catalytic converters are engineered to outperform the restrictive stock cats. The included high flow catalytic converters provide a significant increase in exhaust flow for a measured improvement in horsepower and torque at the rear wheels.
Superior Construction. Stainless Works proudly manufactures their Exhaust Systems right here in the USA. Stainless Works Long Tube Headers are CNC mandrel bent from 1-7/8-inch diameter, 304 stainless steel tubing for superior exhaust flow and long lasting corrosion resistance. These Long Tube Headers feature TIG welded construction, as well as laser cut 3/8-inch header flanges for additional strength and leak-free performance. The Headers merge into a 3-inch collector with merge spikes to optimizes scavenging.
Limited Lifetime Warranty. Stainless Works is so confident in the quality of their exhaust systems that they are backed by a Lifetime Limited Warranty on materials and workmanship.
Recommended Upgrade. AmericanTrucks highly recommends a custom tune with a Handheld Tuner when installing these Headers. By reprogramming the vehicles computer (ECU) you will get the best possible power and performance gains that these Stainless Works Long Tube Headers have to offer.
Not CARB Certified. These Stainless Works Headers are not CARB certified, therefore they are not legal for use in California or any other state adopting California emission standards. Not intended for use on pollution controlled motor vehicles. Not intended for highway use.
Application. This Stainless Works Factory Connect 1-7/8-inch Catted Long Tube Header and Y-Pipe combo kit is specifically designed to fit 2019-2025 GMC Sierra models equipped with the 5.3L V8 engine.
