Let Your Duramax Breathe And Sound Like It Should

If your 2020-2022 Silverado or Sierra 1500 3.0L Duramax still sounds stock, you’re missing out on what this engine can really deliver. The PPE DPF-Back Performance Exhaust Kit transforms your truck with a deep, confident tone and smoother throttle response that you can feel right away. It’s designed to cut down back pressure and let the exhaust flow more freely, which helps your turbo spool up faster and makes your engine more responsive in real-world driving. Whether you're merging onto the highway, towing a trailer, or just want a more aggressive presence, this system delivers without requiring any tuning or complicated mods. The raw stainless steel tubing has a bold, functional look under the truck, while the black ceramic-coated tip gives it a clean finish that stands out without being flashy. Best of all, it bolts up to the factory hanger locations without cutting or welding, so you can get it installed and back on the road quickly. It’s the kind of upgrade that brings your truck to life without changing its character.

Designed To Handle Heat Flow And Everyday Abuse

This PPE DPF-back exhaust system is built for performance where it matters most, durability, flow, and proper fitment. The 4-inch mandrel-bent tubing is made from 304 stainless steel, known for its corrosion resistance and long-lasting strength, especially in harsh weather and road conditions. Each bend is engineered to maintain consistent diameter, reducing turbulence and helping exhaust gases exit faster and more efficiently. The system also features interlocking stainless steel woven bellows, which absorb engine movement and high-heat cycling without stress cracking or failure over time. It includes heavy-duty stainless clamps and uses factory hanger locations to keep the entire system properly aligned and secure under the truck. The black ceramic-coated tip is more than just cosmetic, it resists high heat and helps shed road grime, making maintenance easier. Since this kit installs after the DPF, it keeps emissions equipment fully intact and doesn’t require any reprogramming or tuning. Whether you’re upgrading for performance, sound, or long-term reliability, this system checks all the right boxes.
