      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.
      • Extended Cab with the Standard Box
      • Crew Cab with the Short Box

          Word on the Trail

          My favorite part is that you can put in your trucks make and model, and only shop parts that will fit that truck. Makes life so much easier.
