Description
Rich, Deep Engine Tone. The Magnaflow 3-inch Street Series Black Dual Exhaust System with Side Exits is the upgrade you want if you’re looking to improve your truck’s sound quality. The system includes a straight-through muffler that filters out that annoying high pitch while leaving behind an attractive deep note that’s a real head-turner. With minimal drone and a modulated volume, you can happily go for a spirited drive without the neighbors calling the cops on you.
Leveled Up Performance. More than sound improvement, this aftermarket exhaust system also enhances your truck’s overall performance. As it lowers the backpressure and efficiently facilitates exhaust scavenging, be prepared for that added bump in acceleration and speed.
Durable and Stylish Exhaust Components. Virtually all components that make up the Magnaflow Street Series Exhaust System are made from 100% stainless steel. Stainless steel is not only inherently rust and corrosion-resistant; it’s incredibly strong and stylish enough to be shown off. The tailpipes and tips come with an additional layer of black powder coating that’s perfect if you want to sport that trendy blacked-out look.
Easier and Quicker Installation. Unlike other aftermarket exhaust systems, the Magnaflow 3-inch Street Series Black Dual Exhaust System is designed for a complete bolt-on install. You only need a few hand tools to complete the task.
Application. The Magnaflow 3-inch Street Series Black Dual Exhaust System, Side Exit will fit 2019-2025 5.3L Sierra 1500s without Factory Dual Exhaust.
