      Enhances Performance and Sound. Bring the best out of the 4.3L engine that powers your Chevrolet Silverado 1500 by installing the Magnaflow 3-Inch Street Series Dual Exhaust System - Side Exit. The straight-through muffler design improves the exit of waste gases, and the dual side-exit exhaust tips increase the amount expelled from the engine. As a result, you will get a major boost in horsepower and torque, as well as a more robust sound from the exhaust system.

      Durable and Corrosion-Resistant Construction. This system incorporates 3-inch mandrel-bent tubing and 4-inch dual exhaust tips that are made from stainless steel. This ensures that it will outlast any type of weather exposure and rough-and-rumble driving situation. The entire system has a polished finish to combat fading or corrosion.

      Direct Bolt-On Installation. Magnaflow designed this cat-back exhaust system to be a direct bolt-on upgrade of your Silverado’s stock parts. It will easily bolt straight up to the factory piping without any modifications or special tools required. It should take about 2 hours to complete the task.

      Lifetime Limited Warranty. Magnaflow backs its exhaust systems with a lifetime limited warranty. This means this product is guaranteed to be free from material and workmanship defects for as long as you own your vehicle on which it was installed. Some exclusions may apply; please see manufacturer’s warranty for details.

      Application. This Magnaflow 3-Inch Street Series Dual Exhaust System - Side Exit is specifically designed to fit 2019-2020 4.3L Silverado 1500s without Factory Dual Exhaust.
