Energize Your Machine. Giving your 2009-2013 5.3L GMC Sierra an authoritative new presence with its mellow but strong exhaust note, the MBRP Pro Series 2.5-inch Split Side Exit Cat-Back Exhaust offers a big sound upgrade with its high-flow, chambered muffler. The open design, including the mandrel-bent pipes, provides other benefits also, efficiently scavenging combustion gases to eliminate most backpressure and cool the fumes by 200° F. This removes an obstacle to more cold air drawing into the engine, creating +5-10% gains in horsepower and ft/lbs of torque to strengthen your pickup's performance. As the icing on the cake, this also wins +1-2 mpg extra economy alongside longer oil life.

Top Grade Stainless. The MBRP Pro Series Cat-Back is the highest quality system offered by this company, constructed wholly from T-304 stainless steel. This stainless grade is used for airplane parts due to its nearly total resistance to rust and corrosion. The 2.5-inch tubing has a constant cross-section due to mandrel bending, so it doesn't offer any chokepoints to the exhaust, while the large, bold 4" tips behind either tire are polished brilliantly. This tough system comes with a limited lifetime warranty.

Easy Installation. The installation process of MBRP Cat-Back Exhaust is easy and the exhaust system can be installed with common hand tools. The bolt-on, no weld design provides you with a hassle-free installation process that can be completed in approximately 1-2 hours. Depending on your cab and box size, some cutting to the piping may be required.

Application. The MBRP Pro Series 2.5-inch Split Side Exit Cat-Back Exhaust is designed to fit the 2009-2013 5.3L GMC Sierra's with the following cab and box configurations.
  • Regular Cab with the Standard Box
  • Regular Cab with the Long Box
