Features & Details

  • Stainless Steel Tubing
  • 3" Diameter

Improve Performance. Your Sierra's factory catalytic converter is limiting the exhaust flow and power of your engine, and thus it inhibits your vehicle's performance. Install this replacement Kooks 3 in. Off-Road Y-Pipe to deliver better flow to your exhaust, so you'll enjoy the increased rear-wheel torque, horsepower, and overall performance and driving experience that comes along with it.

Quality Construction. This Y-Pipe is constructed from three-inch diameter mandrel-bent 304 stainless steel tubing, merged in a "Y" crossover to provide a better exhaust flow for your system. Not only does this design help with flow and performance, but it helps create that loud, aggressive exhaust note you love to hear on the road. While this Y-Pipe is great for any driving application, it's especially well-suited for use while off-roading or on the track.

OEM Outlet. Your Y-Pipe features an OEM outlet, which you'll use with the stock exhaust. Keep in mind, this Kooks 3 in. Off-Road Y-Pipe is designed specifically for use with Kooks Long Tube Headers.

Application. This Kooks 3 in. Off-Road Y-Pipe is designed to fit on the 2007 to 2008 4.8L, 5.3L and 6.0L GMC Sierra models equipped with a set of Kooks Long Tube Headers.
