DIESELR Cat & DPF Race Pipe (2020-2022 GM 1500 3.0L Duramax)

The DIESELR Cat & DPF Race Pipe for Duramax 3.0L trucks is built for serious diesel owners who want better airflow, cooler engine temps, and a stronger powerband. Specifically designed for 2020–2022 GM 1500 3.0L Duramax pickups, this system removes restrictive factory emissions components and replaces them with a durable, high-flow T409 stainless steel pipe.

This race pipe retains your stock muffler, preserving a clean OEM appearance and a milder exhaust note, while still offering the performance benefits of reduced backpressure. Precision mandrel-bent tubing and leak-resistant flanges ensure a perfect fit, and TorcTite® clamps make installation fast and secure.

Expect a smoother ride, better throttle response, and lower Exhaust Gas Temperatures (EGTs)—especially important for tuned, heavy-use, or off-road setups.
