Mines a 5.3 with dual exit pipes. I had all of the resonators covered on this video. I don’t have accounts to post the video anywhere and kinda don’t want to create one so if you want to message me your email, I’ll send it that way.

Ok so I’ve waited wayyy to long to do any mods to my truck because I almost got rid of it. Now that it looks like I may be keeping it I’m trying to decide to delete or change muffler. I’ve heard/watched plenty of videos but really couldn’t get a good idea on how the delete sounds at highway cruising. I’ve been on my back for quite some time due to surgeries and I now have that itch. Time to treat myself. For the guys with the delete, is it really loud? And does it drone bad? Last, are you still happy with it or is it too much now? Thanks for your input

No thats a bonus.

I agree.  The wife's  Camaro SS with a stock exhaust does that.  Sounds great!

My 2001 Z71 would do this if I downshifted, so I downshifted....A lot.

 

Unfortunately with cam phasers this wont work on my AT4.

2019 Sierra 5.3. I have clamped the flapper open and taped/covered the screens up. I am super happy with the sound and have been asked what exhaust I was running. They are surprised when I tell them it is factory exhaust lol. The only thing I do not like is that you can see the tape through the fender well when standing beside the truck.

How do you clamp the flapper open?

    • Oil pump noise was discussed before.  I will try to remember to record a remote start later this morning. 
    • There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65
    • On my wife's 2020 Blazer (~69000 miles), we started to notice the brakes pulsating at faster speeds. Typically around town you don't notice anything, but highway/interstate driving you will notice it. I decided to pull of the front tires and look at the brakes. I figured with the milage, the pads should be wearing out to their life span, but they actually looked decent. Still with "meat" on them. One pad has a ridge wearing in it, and that same rotor is showing the ridge too. That's not the concerning part...the other rotor appears to have a raised bump on it!  The picture make it look like a pimple! Very odd and strange! NOTE: These are the factory brakes and rotors.   I'm attaching pictures of the front brakes and what they look like ate ~69000 miles.
