    Gain a More Power. Your Sierra needs all the power it can get. By installing this Kooks 3 in. Off-Road Y-Pipe, you free up more engine power because more exhaust can escape quickly, especially since the Y-Pipe does not contain catalytic converters.

    Smart Design. Fashioned with a 3-inch wide diameter, this pipe offers plenty of space for a fast and high-flow of exhaust. The Y-Pipe is made of stainless steel for rugged durability as well.

    Precise Integration. Made for an exact fit on your Sierra, this Y-Pipe hooks up to the stock Cat-back exhaust point of the OEM outlet. It's used only with Kooks Long Tube Headers for high-powered function and a secure fit.

    Application. Legal in 49 states excluding California, this Kooks 3 in. Off-Road Y-Pipe is designed to fit on the 2014-2018 5.3L GMC Sierra's equipped with a set of Kooks Long Tube Headers.
