2019-2025 GM 3.0L Duramax Turbo Resonator Delete

I recently installed the PPE Turbo Resonator Delete on my 2023 Chevy 1500 Duramax 3.0L, and I wish I had done it sooner. This is one of those simple upgrades that actually makes a noticeable difference in performance and longevity.

Why Ditch the Stock Resonator?
One of the biggest issues with the factory turbo resonator is oil build-up over time. The stock unit tends to collect residue from the PCV system, which can lead to airflow restrictions and gunk buildup in the charge system. Swapping it out for PPE’s resonator delete eliminates that potential problem while improving airflow.

Instant Benefits
Right away, I noticed quicker turbo spool-up and smoother throttle response. The truck feels more responsive, especially when getting into the throttle. Plus, the turbo sound is more pronounced—you actually hear the whistle and airflow, giving the Duramax a bit more personality without being too loud.

Better Flow, No Drawbacks
This is a zero-risk upgrade—no check engine lights, no tuning required, and it fits perfectly with stock components. Just better airflow, less restriction, and no more oil pooling in the intake system.

Install – About an Hour
It took me about an hour to install, making sure everything was seated properly. The fitment is spot-on, and PPE makes the process simple with a clean design that replaces the bulky stock resonator.

Final Thoughts
If you’ve got a Duramax 3.0L, this is a must-do mod. Better throttle response, improved turbo efficiency, reduced oil buildup, and a cleaner intake system—all for an easy, affordable upgrade. Highly recommend!

Install was quick and easy. Small change in tone. Overall pleased with the product.

Some people have said this will change the tone, but I haven't noticed any difference. Looks great, fits great.

Its changes the tone, and hearing the turbo slightly.
