Just noticed it a bit for the first time the other night on the highway. Didn’t really bother me that much. Was mild enough to forget about it after noticing. I think I had to turn down the radio to even figure out what it was. Haha 
 
6.2 with the Touring here as well. Totally love the exhaust overall. Wouldn’t change a thing. 
I drove across the country and had no issues with the exhaust sound at all. I didn't notice a drone sound.

I'm another with the GMPP exhaust, but I also have the GMPP CAI too. It's quiet while crossing at highway speed, but put the throttle down and it rumbles to life. Sent from my SM-N960U using Tapata

Pretty sure the GMPE and the Borla Touring are exactly the same.  Regardless I love my GMPE.  Growls to life on a cold start but isn't going to wake the neighbors.  My daughter tells me she likes it w

My 5.3L GMPE does drone a little above 65mph on slight inclines... basically when it's running between 1600-1800 RPM, right before it would downshift. 

 

It was a little alarming at first, but then I got used to it. It also alternated between a droning sound and the exhaust sound itself... but there are times when it is definitely a resonating drone noise. 

 

All this to say, I'm not at ALL dissatisfied.

Since it alternates between drone and exhaust sound, I wonder if the drone is when it's in V4?  The Borla GMPE has a flapper to help with the helicopter noise when in V4 but wonder if it effects the drone too? Interestingly enough I just got a call from the dealer that my exhaust is finally here!  Going to pick it up and put it on this weekend.  Mines a 2017 but shouldn't be much different sound wise from the 2019/2020's.  Will report back with thoughts.

 

Separately... This will be my second purchase of the performance exhaust. First go round I ordered off one of the big on-line parts company's and they send me the wrong one. (I ordered the right part# but what they sent me doesn't fit) But in my haste to get it put on I threw away the box before I realized it didn't fit, and now they will do absolutely for me about getting an exchange or refund so I'm out $1,000, and now another $1,000 on this new one. Expensive lesson.

 

I can't say 100% what it fits but appears to be for the 5.3 due to the 3 inch pipe and possibly for a 2019/2020 crew cab short bed. The hangers didn't line up right and was about 2 inches short to connect up at the front connection. But regardless I'd think the muffler could be used in most any application with a little welding.  So it's sitting in my garage as an expensive paperweight.  If anyone is interested I will let it go for any reasonable offer.  I'm in Chicago area for local pick up or will be willing to deliver with in reasonable driving distance... Brand new and unused, but no box.  I just can't definitively say what make/model it goes to other than it is for the 5.3. Accepting any offers at this point

There is no flapper valve on the GMPE for 6.2. Its simply 3.5” back to the Y into 2.75” duals with one muffler

There isn't one on the GMPE for the 5.3L, either.

The Borla GM Performance Exhaust does. It's make by Borla to GM spec. which includes the flapper. Had one on my prior truck as well.  I'll try to snap a few pictures, but it's before the muffler where the stock flapper is behind the muffler.  But this is for pre 2019 models, so that could have changed with 2019/2020.

T1 has no flapper for DFM engines

Guess I am somewhat confused now.  If the Borla touring and GMPE were sitting next to each other would there be any differences?  Flapper or resonators?

There are no flappers or resonators on the Borla Touring or the GMPE systems. For 6.2L or 5.3L for 2019+ T1 trucks. 

 

It would be very hard to tell the difference if they were laid out next to one another.

Great....I am getting to old to figure all this out.  Think I will order the touring.  Might wait to install until after I figure out the GM valve recall.  My truck appears to fall in the date range.  Built July 2020.

It's not a recall. They only issued a TSB. They won't do anything until something breaks. My truck was built in June 2020, so I'm in the same category. My truck was at the dealership last week getting offroad lights wired in. I asked them to take a look and showed them the TSB. They said nothing was wrong at the time of inspection, so they weren't going to touch it. They also looked for a leak in the rear window and found nothing.

GMPE doesn't have quad tips. Quad tips are another accessory.

Here’s the GM part number and link to what I ordered from the dealer. If you get it as an option from the factory it comes with the standard tips. For the 6.2 the only option of you install it after delivery is quad tips:

      Tire psi

      By jgaudet99 · Posted

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol

      Tire psi

      By Chuck FB · Posted

      You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !

      Some Assembly is Required

      This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.

      Tire psi

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.
