MagnaFlow 19-23 GM 1500 4.3L / 5.3L D-Fit Muffler Replacement

This MagnaFlow D-Fit Muffler Replacement kit gives your 2019-2024 Chevrolet Silverado 1500 or GMC Sierra 1500 (with 4.3L or 5.3L engine) a performance upgrade by swapping out the factory mufflers. It replaces the mid-body section of your exhaust, featuring a fast-flowing, 3-inch mandrel-bent main piping that guides exhaust gases through a 14-inch straight-through performance muffler and an 11-inch NDT (No Drone Technology) resonator. This setup is designed to enhance your truck's exhaust note and performance without the annoying highway drone, thanks to MagnaFlow's specialized resonator technology.

Built from durable 409 stainless steel, this system is constructed using advanced CNC precision robotic manufacturing techniques, ensuring a solid build that's made to last. The direct-fit design means it utilizes clamp-on inlet and outlet connections, making installation straightforward without the need for welding. This kit is compatible with most 2019-2024 Silverado 1500 and Sierra 1500 models equipped with the 4.3L or 5.3L engines, though it's important to note it's not compatible with factory performance exhaust options.

You'll receive the main muffler and resonator assembly, designed to integrate with your existing OEM piping and tailpipe. MagnaFlow backs this system with a limited lifetime warranty, giving you confidence in its longevity and performance.
