      Description

      Deeper and Bolder Exhaust Sound. Equip your 4.8L Sierra with an excellent exhaust upgrade for a powerfully deep sound by installing this Dynomax Ultra Flo Welded Dual Rear Exit Exhaust System with Polished Tips. Dynomax specifically designed this exhaust system to produce aggressive exhaust notes that enhance your truck’s outdoor confidence. It is equipped with CRF technology to deliver a deeper, intense sound.

      Optimized Engine Performance. Designed to give your truck impressively enhanced performance, the Ultra Flo Welded Exhaust System features smooth mandrel-bent tubing and free-flowing, well-designed muffler. These characteristics enable the exhaust gases to pulse out more efficiently and in higher velocity with the least amount of restriction, giving your vehicle remarkably powerful driving performance.

      High-Grade Stainless Steel. The Ultra Flo Welded Dual Exhaust is constructed from heavy-duty stainless steel that exhibits exceptional tensile strength. This high-quality construction can handle tremendous temperature and pressure to deliver lasting performance. Furthermore, the superior craftsmanship and fully welded tubing ensure that there is no leakage for more efficient operation. It also includes a pair of 3-inch, polished stainless steel exhaust tips to complete your Sierra’s commanding stance.

      Seamless Compatibility. Dynomax designed this Ultra Flo Welded Dual Rear Exit Exhaust System for a bolt-on installation. It is seamlessly compatible with the truck’s factory hangers and can be installed using basic hand tools with light to moderate mechanical skills.

      Application. This Dynomax Ultra Flo Welded Dual Rear Exit Exhaust System with Polished Tips fits all 2009 to 2013 4.8L GMC Sierra 1500 models.
