Especially when cold in the garage.  Sound like an exhaust leak but it isn't.  I can even hear it occasionally when cruising under very light throttle.  Sounds like it under the passenger floorboard.

I hear the same noise.... especially when you drive by a wall on the passenger side you can hear it coming back at you and it's only when you lightly tap the throttle.... Interested as well!!! Drives me crazy, I hear everything in cars.

I have/had this on my 3.0 diesel. I got under the truck, remote started it and moved my exhaust around. I think the noise is from the flexible connector on the exhaust. I did manage to get rid of the noise by putting 175lb tension duct straps around the exhaust isolators towards the rear of the truck to tighten them up. The noise instantly disappeared and has not been back since. 
 

The noise very slowly got worse until I did something about it, so I’m guessing the isolators start to loosen up and sag over time which allows the exhaust to vibrate just right to rattle the flex connector. Also worth noting is that the isolators themselves feel to be made from a softer rubber than others I have seen in the past.

Thanks for the help.  I do not believe that is the sound I am hearing.  My truck does it with the stock exhaust and Borla Touring.  I don't think the noise is something that is "wrong", I would just like to know what it is.  Worse when it is cold and can hear it when warm under part throttle.  Sounds like a rattle or exhaust leak.

Mine sounded exactly like a rattle/exhaust leak, maybe even a heat shield rattling against something. It actually sounded loudest as if it was inside the DPF. I had no check engine lights and when I floored it or even just got on it, I did not hear it. Only at idle or very light throttle. Until I actually moved that flex connector around, I did not suspect it to be the cause, but even a little movement makes the sound come and go away. Just pulling/pushing up on the exhaust tip gets rid of the sound, I think it has to do with the alignment of the exhaust. Here’s some pictures of what I did.

I have a 2020 Silverado RST 6.2 and had a tapping/ticking noise heard from the passenger side front of the vehicle around the front passenger floor board I feel I heard it most or was worse the faster I drove or more noticeable at 50+ mph. The dealership found the j clip used to secure the wheel liner or mud flap on the passenger front was hitting the body side and as soon as they repositioned or adjusted the noise went away. hope this helps.

Ok guys,

 

It is not the exhaust vibrating and its not the wheel liner. (verified these two) Most noticeable at cold idle and while driving with slight throttle in a high gear at low RPM.  Sounds like a can full of marbles.

For the Duramax folks:

 - there may be an unnecessary exhaust isolator

 

https://gm-techlink.com/?p=13612

 

Duramax Diesel Exhaust Isolator No Longer in Production

August 31, 2020

A missing exhaust isolator (Fig. 5) on 2020 Silverado and Sierra models equipped with the 3.0L Duramax diesel engine (RPO LM2) and the single exhaust system (RPO NB5) should not be installed as part of a warranty claim at the dealership.

 

F05-exhaust-4.pngFig. 5

 

The exhaust isolator is no longer installed in order to address a noise concern. However, the exhaust hanger on the frame and the hanger on the exhaust pipe are still in production. The exhaust hanger on the other side of the exhaust pipe near this location is still connected. (Fig. 6) These changes went into effect at the Fort Wayne assembly plant on June 17, 2020 and are part of the continuous product improvement process. Light-duty trucks with the diesel engine and single exhaust built at the Silao assembly plant have not yet removed the isolator from production.

 

F06-exhaust-2.pngFig. 6

 

The exhaust hanger was communicating an exhaust boom due to a structural vibration. Without the isolator connecting the exhaust pipe to the hanger, the boom sound is eliminated. At the same time, it was determined that the hanger is not needed at that location on the exhaust pipe and that durability and the function of the exhaust are unaffected.

If an exhaust isolator is installed on the exhaust pipe and connected to the hanger, the exhaust boom sound may be heard. A warranty claim should not be submitted for installing the exhaust isolator.

TIP: The Electronic Parts Catalog may show the eliminated exhaust hanger on the single exhaust pipe. The catalog is currently being updated to remove the hanger.

Good update but not my issue.  This only applies to the Diesel with a single exhaust system.  It's also not the same noise.  ?

I know.

It was for some of the 3.0 owners that were posting/following. 

 

Is your noise the high pressure fuel pump?

‘Can full of marbles’ sounds are usually caused by either exhaust leak, heat shield rattle (temperature can affect this), or more likely something inside the catalytic converters is loose. Could also be the exhaust flap being loose in its mounts I suppose. 
 

Kind of off topic now, but removing the exhaust isolator for the duramax exhaust only made it rattle and more noisy, plus I could feel the exhaust swinging side to side with it removed. The problem is they got the exhaust for it from Pep Boys on clearance lol. Ray Charles could have put down better looking welds. I’m surprised they even hold together. They definitely wouldn’t hold even 50psi.

      OCI, not when but why?

      By KARNUT · Posted

      But Grumpy I did show several subdivisions that had homes starting in the 170K range. If you bought a Townhouse or Condo you could go cheaper. Same with a car 3000 dollars in the 70s translates to around 20K today. There are several models at that price. You actually get more for the money. In the 70s I drove a 3000$ car bought a 28K home and made 4.50 per hour. Thank goodness for overtime. Today I could buy a 170K house drive a 20K car and make 25 dollars an hour operating the same machine today. The difference the house, car, machine would be better and have AC. And I wouldn’t be taxed on overtime. And statistically your wife works too. Easing the burden. I thought we agreed to disagree. I brought receipts earlier, showing examples. I think you’re more stubborn than me. I was done with this debate.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.
