Overview
Give your 2020-2022 GM 3.0L Duramax a stronger tone and improved performance with PPE's 304 Stainless Steel DPF-Back Dual-Exit Exhaust Kit. This free-flowing system reduces back pressure, enhances turbo efficiency, and delivers a clean, aggressive exhaust note. The polished tubing paired with black ceramic-coated quad tips creates a bold, high-contrast look.
4-Inch 304 Stainless Steel Tubing
The system is built from full 4-inch mandrel-bent 304 stainless steel, offering excellent corrosion resistance and long-term durability. It replaces the factory muffler and runs from the diesel particulate filter back to the tailpipes, using all OEM hanger locations for a precise fit.
Quad Black Ceramic-Coated Tips
A set of 4-inch round quad tips finished in black ceramic gives the rear of the truck a modern, aggressive appearance. The ceramic coating provides heat resistance and a premium finish that pairs perfectly with the polished tubing.
Improved Flow & Turbo Response
By reducing restriction in the DPF-back section, this system helps improve fuel economy, lower manifold back pressure, and sharpen overall engine response. The factory exhaust valve is retained for proper operation.
Direct Bolt-On Installation
The kit includes all required hardware and 304 stainless steel clamps. Installation is straightforward, using factory mounting points throughout.
