Next Saturday, Lord willing, i am getting my exhaust done on my 5.3 2019.  Getting the muffler replaced with pipe and some 6” slash cut tips welded at a angle.  The stock hdmi port looking tips are likely going to stay in because the hole might look weird.  Anyone done something similar and got any advice/experience?

I’m sure you’re aware of cylinder deactivation. Be prepared for weird exhaust sounds that come with.

You doing straight muffler delete ? I know a lot of guys say it’s fine( Pre 2019 is actually). But it sounds like ******. Drones horrible for some reason on newer trucks. I have 6.2 but 5.3 will be similar.

Before I bought my current truck, I test drove a 2020 GMC with the 6.2.  The previous owner had the flappers, muffler and resonators removed and some kind of aftermarket muffler installed.  The minute I drove out of the dealer's lot, I knew I wouldn't buy the truck.  Fairly loud in the cab and lots of drone at highway speeds and the noise it made when DFM kicked in was hideous.  Even the salesman was like "yeah, we're gonna have a hard time selling this one."

Well today i got it done and i ended up going full send and getting true duals with the third cat cutout straight back to 6” tips no mufflers. And let me tell you she loud as heck.  I took her on the interstate and the cylinder deactivated thing wasnt very noticeable and didn’t bother me.

With that exhaust ( bin there done that) your ears are probably ringing drowning out that helicopter sound. I hear it with stock exhaust. On Rams Too.

soon as you replace the exhaust or remove the resonators on a factory exhaust on 5.3 or 6.2 the helicopter AFM/DFM is annoying as hell pretty much everyone who does either will end up disabling DFM/AFM

      Tire psi

      By jgaudet99 · Posted

      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.

      Gas Prices

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.
