Description
Better Flow for Improved Performance. If you're looking to improve the power and performance of your GMC Sierra 1500, you need the Stainless Works 1-7/8 in. Headers with Catted Y-Pipe. Working together, the factory connects long tube headers, High-flow cats, and Y-pipe increase your vehicle's exhaust flow, delivering far superior rear-wheel torque and horsepower over your factory exhaust system.
Stainless Steel Construction. The Stainless Works 1-7/8 in. Headers with Catted Y-Pipe features quality construction that's built to last. The 1-7/8 in. mandrel-bent long tube headers are made from 304 stainless steel tubing, which not only improves exhaust flow but also resists corrosion. TIG-welded construction and extra thick, laser-cut, 3/8 in. flanges add even more strength and solidity to the system. The headers meet at a 3-in. slip-fit collector with merge spikes.
Installs with Factory Cat-Back System. This "Made in the USA" kit is install-ready, including clamps, extensions, bolts, and RTV silicone. The Stainless Works 1-7/8 in. Headers with catted Y-pipe installs directly with your Sierra's existing factory cat-back system.
Application. The Stainless Works 1-7/8 in. Headers with Catted Y-Pipe fit 2007 to 2013 5.3L GMC Sierra 1500 models with the following cab and box configurations.
