These new gen trucks don’t get too loud. My buddy has a 2020 6.2 straight piped and it’s not that loud. The flow master 40 and 44s are too quiet on these truck. If your going with a flow master then get the 10 series. 

You have obviously not heard ATAK's on the 6.2 then, nobody would consider them not loud

I'm in the same dilemma.  I don't mind it "Corsa Sport" loud when I'm on it or even on startup and idle but when I'm just cruising on the highway with the kids, I don't want to really hear it at all.  I've posted on the Facebook groups to try and find someone with a muffler delete local to me (Lawton OK).  I also plan to visit the dealer to look and hear the Borla Touring cat-back.  If the delete is too loud, i'll spend $1200 on the full cat-back but saving $1000 bucks is definitely tempting and worth the investigation!!

Muffler delete would not be for you, I would not suggest it.

 

Borla Touring quite a few owners enjoy, same muffler as the GM performance exhaust and in my opinion the quietest borla muffler available.  If your just looking for a little sound on startup and when you give it some gas, Touring is the direction I'd suggest

I did the delete.  I was only slightly too loud but went with 3.5" pipe to replace the gap left by cutting out the muffler and got bad drone at 1500 rpm.  Installed a Borla XR1 and got the proper volume but still had the drone.  Went back stock without the flapper until I can justify $1200 for sound.

Contrary to what people always say, Borla has drone when you all straight pipe. It can be minimal but it is still there. I’ve heard keeping a single flapper or two removed the drone completely but you will sacrifice some sound volume. 
I have the ATAK setup, I love It, no flappers and barely any drone but it is there at times. It is loud though. 
I have heard good things about the type S muffler, little quieter but still gives off the sound that’s missing with the touring muffler. 
IMO the gm perf exhaust isn’t worth it because of the touring muffler.  Isn’t loud enough for me nor do I think it’s worthy of the price point, which is why I went custom setup instead.

Could you take a clip of this inside/outside?

 

A lot of people are pulling the muffler and keeping the flapper which makes little sense to me since it is a pretty large restriction.  Even when fully-open, it appears to block off +/- 30% of the space.  IMHO, if I'm going to get a little louder, I should also be freeing up restrictions

I already went back to stock and deleted the flapper.

I think the problem was that the XR1 was a straight through muffler..... I feel if it had baffles inside to change the air and sound wave flow it would have been better.

That is what I am interested in hearing.  Stock muffler without flapper.  I've got a saw and welder :)

Might as well go muffler delete at that point.

It’s all in the setup. I’ve had straight through designs on all my cars, no drone issues. Truck is different than car obviously, and I’m not going to put the same $$ into my exhaust system as my cars. Your not wrong though, chambers would help but so would the flappers. Anything that would impede exhaust flow will cut down on drone, but will also hamper tone and to a degree performance. Just comes down to what you want from your system.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences. "an account based on fact; a blur of fact and fancy." Something demonstrated to exist or known to have existed. "Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact." A real occurrence; an event. "had to prove the facts of the case." The American Heritage® Dictionary of the English Language, 5th Edition • More at Wordnik   If you'd like to disagree call your Senator or Representative and let him know his departments are in error. But you and I? We are not doing this.

      Transmission jumping out of gear while driving.

      By JimCost2014 · Posted

      Probably a one and done post, but do you have a CEL on the dash? Was having issues with my transmission, fortunately only a week, and it turned out to be the transmission harness. Valve body was in good shape, so new harness with all the sensors attached, new fluid, and filter. Seems to have worked so far?

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      Two interesting tidbits of information which are NOT related were just released.   One, regarding the possible thrust bearing issues / engine failures with the 3.0. Demonworks just did a segment in which they believe they may have found "a" or "the" cause of thrust bearing failures: A missing thrust bearing. If the engine doesn't have all its thrust bearings from the factory, the missing bearing can cause extra play which ends up destroying a nearby thrust bearing which then sends metal through the engine.       Of other importance, Lake Speed Jr released some interest information regarding oil weight selection for the 3.0. Comparisons of:   AcDelco 0w20 Dexos D Mobil 1 ESP x2 0w20 Dexos D Mobil 1 ESP x2 0w30 Mobil 1 ESP x4 0w40. Mobil Delvac 5w40   Spoiler alert: The Mobils are PAO Ester -base and the ACDelco is a Group III base. Mobil shows lower wear in their tests for similar weights. Additive packages between 20-30-40 weight ESP's appear to be the same, but only 0w20 is Dexos D licensed. Wear is even more reduced with 30 and 40 weight ESP although all perform very well and resist shear and provide very similar viscosities within temperature operating ranges in the 3.0.   There are even more surprises, so just go watch it.

      Weird click noise when revving my truck?

      By JimmyB4 · Posted

      Hello Guys I'm new to the form,         I just put a 7-inch Rough Country lift on my 2016 GMC Sierra 1500 with the 5.3 and I also put a Borla exhaust on it. But I noticed when I'm in park or in neutral and then I rev my truck up really quick there is a bad click noise and I think it's coming from the motor somewhere. Anyways I got a video of it I will attach below I was just wondering if you guys think its rod knock or lifter tick or something like that because I know the AFM kind of made the lifters weak on these trucks.       Thanks!!!!! RIP - Chevy 5.3 IMG_6043.mov

      By KARNUT · Posted

      We’ll have to agree to disagree. I didn’t experience or know anyone who had a decent car after 100K miles in the 60s through the 80s that were daily commuter vehicles. Unless they were collector vehicles. Of course things cost more due to inflation. But we also make more money. The biggest money drains these days are things people think they need today versus what we require back in the day. Like cell phones and internet as examples. Another example is where you live. Cost of living varies from state to state. I would need twice the money to live in NJ vs Texas in retirement. The car you recently purchased was less than my first car with inflation at 3000$ in 1973. I didn’t have air, electric windows, cruise etc. Purchasing power is equivalent, you just have to do the research.
