      Exhaust Upgrade. The Borla Touring Cat-Back Exhaust System - Split Side Exit will give your 2007-2013 4.8L GMC Sierra a huge boost in horsepower. You'll increase your exhaust velocity for more power, better fuel economy and a beautiful roar.

      300-Series Austenitic Stainless Steel. For a premium system, you need premium steel. Borla uses 300-Series Austenitic Stainless Steel, not some T-400 knockoff like 409 that competitors use. A single 2.75” pipe flows into the muffler and dual 2.25” pipes flow out into a split side exit configuration.

      Million-Mile Warranty.
      Confidence in their materials and computer-controlled CNC manufacturing process allows Borla to offer their million-mile warranty. It’s a great way to feel peace of mind on top of the increased flow and power provided already by such a high-quality exhaust system. Ultra-smooth mandrel bends provide max gas flow and therefore maximize the increase in your GMC Sierra’s horsepower.

      Before disassembling your current exhaust system, it’s important to check all components of your installation kit are available. Follow the instructions closely and carefully for the best results. Check the clamps after driving the first few hundred miles and re-tighten them if needed.

      Application. This Borla Touring Split Side Exit Cat-Back Exhaust is designed to be used on the 2007-2013 4.8L GMC Sierra's with the following cab and box configurations.
      • Regular Cab with the Standard Box - 2009-2013 Model Years Only
      • Extended Cab with the Standard Box
      • Crew Cab with the Short Box
