Unlock The Sound And Power Your Duramax Deserves

If your 2020-2022 Sierra or Silverado 1500 3.0L Duramax is still running a stock exhaust, you're leaving sound, performance, and efficiency on the table. The PPE DPF-Back Performance Exhaust Kit is designed to wake up your truck with a deeper tone, quicker throttle response, and improved fuel economy. With free-flowing 4-inch mandrel-bent tubing and a high-quality stainless steel build, this kit helps reduce back pressure at the manifolds, which means your engine can breathe and perform the way it was meant to. The single-exit setup keeps it clean and aggressive, while the oversized 5-inch polished tip gives it a bold, finished look. You’ll notice the difference on your daily drive, towing up steep grades, or hitting the backroads with gear in the bed. Installation is straightforward with a bolt-on design that uses your factory hanger locations, so there’s no cutting, welding, or hassle. Whether you're after better performance or just want your truck to sound like it should’ve from the factory, this system delivers both in a package built to last.

Built To Handle The Heat And Keep Flowing Strong

Behind the polished tip and smooth sound of this system is a fully engineered exhaust upgrade designed for durability and performance. The PPE 117050030 kit features mandrel-bent 304 stainless steel tubing that maintains consistent diameter through every bend, helping to preserve exhaust velocity and reduce restriction. Its interlocking stainless steel woven bellows are built to flex with vibration and thermal expansion without cracking or leaking over time. The raw tubing finish is ideal for those who prefer a no-nonsense, industrial look under the truck, while the polished tip adds just the right amount of flair at the exit. Stainless steel clamps are included in the kit to ensure a tight, corrosion-resistant seal that holds up under high heat and long-term exposure. PPE designed this as a true DPF-back system, meaning it replaces everything from the diesel particulate filter to the tailpipe, all while keeping emissions equipment untouched and compliant. With a limited lifetime warranty on the stainless components, this system is made to outlast tough conditions, heavy workloads, and daily driving without compromise.
