Give Your Duramax A Stronger Voice And Smoother Pull

The PPE DPF-Back Performance Exhaust Kit is a great upgrade if you want your 3.0L Duramax to feel more responsive without going over the top. From the first drive, the engine feels less restricted, especially when rolling into the throttle or climbing grades on the highway. The sound is deeper and more refined, giving the truck some attitude while staying comfortable for daily driving. The dual exit layout with black ceramic coated quad tips adds a bold finishing touch that really stands out from behind. Because the factory exhaust valve is retained, the system stays quiet when cruising and opens up when you need it. It is the kind of upgrade that makes the truck feel more alive every time you drive it.

Built From Premium Materials With Factory Fitment

This exhaust system replaces the factory components from the diesel particulate filter back, improving flow while maintaining emissions equipment. It is constructed entirely from mandrel bent 304 stainless steel tubing, offering excellent resistance to corrosion and long term durability. Unlike lower grade materials, 304 stainless holds up well in harsh weather and road conditions. The system eliminates the restrictive factory muffler to reduce back pressure and improve turbo efficiency. Polished stainless tubing paired with black ceramic coated quad tips delivers a clean and aggressive appearance. Designed for 2020-2022 GM 1500 Sierra and Silverado models with the 3.0L Duramax, this kit installs using factory mounting points and includes all required hardware for a straightforward install.
