      Hit the Gas and Let It Rip. When you're ready to take your stock exhaust and throw it out the window (figuratively, of course), then you're ready for the dB Performance by Corsa 3 in. Sport Cat-Back Exhaust w/ Polished Tips. With superior design and lasting quality, this system will put stock to shame and make you giggle like a schoolboy whenever you hit the gas. 

      Stainless, Flawless, What's the Difference? When it comes to this full cat-back system, the two are one in the same. The full stainless steel tubing means that this exhaust system is protected against corrosion and weathering effects, while the mandrel-bending of the tubing ensures the maximum amount of airflow throughout your system, helping you get an extra 10 WHP and 14 ft lbs of torque.

      Straight-Thru Muffler. The muffler on this exhaust system provides the big beefy sounds you get when you put the pedal to the metal, and its all due to dB's excellent straight-thru design. To finish everything off in style, twin 4-inch slash exhaust tips have been polished and engraved with the dB logo. 

      Installation. This cat-back system is most painlessly installed when you have access to a car lift and a quality set of hand tools. A friend is also recommended to help hold pipes in place. Installation should take about two hours. 

      Limited Lifetime Warranty. The limited lifetime warranty provided by Corsa protects against manufacturer and material defects.

      Application. This dB Performance by Corsa 3 in. Sport Cat-Back Exhaust w/ Polished Tips - Split Rear Exit is designed to fir 2007-2013 4.8L GMC Sierra 1500 models. Ensure correct model and engine before purchase. 

      Technical Note. Requires the use of the factory hanger and rubber isolator part number 15740212.
