2020-2026 GM 3.0L Duramax Turbo Resonator Delete

Took 30 minutes to install. Minimal sound improvement but enough to notice. Built well, looks great. Would recommend.

Better looking and smoother airflow. I can hear the turbo a little better. Just dont expect it to be way louder. Sounds cool when the engine turns off. Same as the intake tube, fits better and easy to clean. Comes with a Viton o-ring. It fits really tight and it can be a little hard to install. Use leverage from the fender or the turbo....dont the intake manifold..you can crack it because that is made from plastic. I noticed a better turbo response time. If you are going to upgrade to their Intercooler, save your money. The Intercooler will comes with its own delete pipe. Same with the upgraded silicone tube for the turbo resonator delete pipe. The Intercooler comes with it. If you do want to get the silicone pipe upgrade, a pic is supplied. Thicker than stock and insulated better

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!

Super simple a installer, pièce de tres bonne qualité et bien fait ,j'aurais aimer avoir la nouvelle génération mais out of stock mais celle-ci fait le meme travail et est vraiment efficace donc c pas une déception dutout .

Simple little mod that helps defeat oil buildup in the plastic resonator. Can definitely hear the turbo a bit more on spool up and blow off, but otherwise this is just a quick and easy risk free mod, that will only help in the long run.

I had an afe power resonator delete on prior to the ppe. Every year I would have to change the very small oring due to oil leakage. I installed the ppe and you could tell the sealing difference right away. Definitely a quality part

PPE provide clear instructions on auto do this 30 minute max install. You can tell this product of high quality just by looking at it 10 out of 10 on easy mod to help with maximizing airflow for the 3.0L.

Very pleased with the Duramax Turbo Resonator Delete. High quality. I haven't seen a big difference yet, but it has to help with airflow to the turbo. Anything that aids in better air to the engine and turbo has to help with fuel economy and power.
Overall, very happy with this addition to my engine.

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.
