Description
Improved Truck Engine Acoustics. Give your Sierra a powerful voice with the Magnaflow 3-inch Street Series Black Dual Exhaust System with Rear Exits. This exhaust overhaul will not only result in a performance boost, it will also provide your truck with a more authoritative growl, minus the drone. What’s more, a straight-through muffler modulates the volume so you can freely accelerate without waking up the neighbors.
Designed for Better Performance. This exhaust kit contains components that are designed to work together to bring you a more efficient exhaust operation. As a result, you can expect some boost in acceleration and speed on the streets and on the trails.
Premium Stainless Steel Material. Every component of this Magnaflow Street Series Black Dual Exhaust System is made with stainless steel, from the pipes to the clamps they come with. That’s why you won’t need to worry about corrosion building up over time. More importantly, the 3-inch diameter pipes feature mandrel-bends to ensure the elimination of some backpressure and better exhaust scavenging.
DIY Installation Made Easy. While Magnaflow recommends a professional installation, you won’t really require it. The Street Series Black Dual Exhaust System installs without the need for modifications like cutting, drilling, or welding. It’s a bolt-in system that uses factory connection point, in fact.
Application. The Magnaflow 3-inch Street Series Black Dual Exhaust System, Rear Exit will fit 2019-2025 5.3L Sierra 1500s without Factory Dual Exhaust.
