The MagnaFlow Chevrolet Silverado 1500/GMC Sierra 1500 D-Fit Muffler Replacement with Muffler Performance Exhaust System #19533 enhances your rig with dyno-proven performance while replacing your truck's OEM mufflers. The clamp-on inlet, clamp-on outlet design facilitates easy installation. #19533 features fast-flowing, 3" mandrel bent main piping that passes through a 14" straight-through performance muffler and 11" NDT (No Drone Technology) resonator and is compatible with all 2019-2023 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with the 4.3L or 5.3L engine options (except those with the factory performance exhaust option). MagnaFlow's No Drone Technology helps minimize the droning that you might otherwise hear while cruising at highway speeds. This system replaces the mid-body section of your OEM exhaust system. This Silverado 1500/Sierra 1500 exhaust kit is made of durable stainless steel and produced using advanced CNC precision robotic manufacturing techniques, all backed by MagnaFlow's limited lifetime warranty.

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.

    Donald Wojnar

  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.

    Adam Cranston

  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

    Bryce Budd

  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.

    William Brunell

  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
