      Performance Boost. Boost performance potential by replacing your 5.3L GMC Sierra’s factory exhaust with Borla’s Touring Cat-Back Exhaust System, while also improving fuel economy. The split side exit system features a straight-through muffler design that increases exhaust flow and mandrel-bent exhaust tubing for optimal volume and exhaust gas velocity.

      CNC Manufactured. Borla proudly makes the Touring Series Cat-Back Exhaust in the USA, achieving precise fitment. The long-lasting, durable system includes top-quality stainless steel tubing and two aggressive-looking 4-inch round, rolled, angle-cut stainless steel tips exiting behind the rear tire.

      Custom Fit. Borla provides an exhaust custom fit to your Sierra for an easier install and better performance. The kit includes everything necessary for the bolt-on installation, including the oval muffler with single 2-3/4-inch inlet and dual 2.25-inch out. Borla warrants this quality exhaust to be free of craftsmanship and material defects for one million miles from the purchase date.

      Distinctive Sound. The distinctive Borla Touring Exhaust sounds deep and throaty during acceleration and has a mild note while coasting that is slightly louder than stock.

      Application. This Borla Touring Split Side Exit Cat-Back Exhaust is designed to be used on the 2014-2018 5.3L GMC Sierra's with the following cab and box configurations.
      • Double Cab with the Standard Box
