Has anyone messed with the flappers at all? I’m just doing a muffler swap this week but I’m absolutely lost when it comes to the flappers. I want as much noise as I can get without droning at highway speed or too much noise at cruise. I got a Magnaflow 11229 muffler. Question is, do I cut both flappers off or only one? If one, which one? I’m thinking the upstream flapper will kill more drone than the downstream. I read on another post that both flappers removes makes too much drone

Cut it off!!

Hello all.  The GM Performance systems for the 2019 Silverados are indeed made by Borla. They are made according to GM's specifications and are separate from the aftermarket Borla systems.

That’s not a flapper in that picture, it’s the resonator for the 5.3L V8. Moreover, if you’re going with this muffler (magnaflow 11229) on the 6.2L V8, do NOT cut off both flappers unless you want to drive yourself batshit having a helicopter flying under your truck at any speed over 35...

Check out the following part numbers.  Borla offers all their tip options with the dual system.  

 

PNs 140778, 140779BC, 140779CF, 140785

 

 

I’m looking at the true dual systems too but can’t find any sound clips so or comments regarding sound with DFM so am a bit hestitant.

 

Buy the Diablosport tuner and disable the DFM. Problem solved.

The Diablo sport (and all other tuners currently on the market) does not work on the new body style Silverados. It only works on the LD/Legacy edition.

Go check the DiabloSport website... I confirmed with customer service last week that the tuners only works correctly on the 2019 LD. Yes, it can disable AFM on the new 5.3 technically, but it cannot disable DFM on the 6.2. AFM and DFM work entirely differently

I’m telling you it does not tune the 2019 new body style 6.2L. So is Diablo Sport as of last Tuesday. Just because Summit racing says it will work does not mean that’s correct. Diablo Sport initially announced that it would work on the new bodies back in 2018, but it didn’t, so Diablo Sport removed it from their own site under the 2019 Silverados other than the LD. Many 3rd party websites never updated their listings. Go ahead and spend your money on it if you want, but don’t get upset when it doesn’t work.  The only tuner currently available is from HP Tuners and you have to replace the entire ECM, costs about $3000 minimum.

Nothing sounds like a borla!!  It's the best. Hands down. 

I must agree. For the T-1 platform. I had Corsa on my 04 Pro Sport Sierra. It was awesome. I put the same Corsa system on my 12 Sierra 5.3 SLT and it was much quieter, so much so that I called Corsa. I was informed due to AFM the system muffler design was different, necessitating a much more subdued tone.

 

 The Borla system, even though I went with S type, is much more pronounced. It has a deep, throaty growl that sounds fantastic. Very happy with it!

Wanted to share, as I had a hard time finding comparisons for the new 2019/2020 Silverados.  I was going back and fourth between touring and s-type, leaning more towards the touring, until I listened to the videos in my truck, with its sound system.  Computer speakers and cell phone speakers just don't do it justice.... need to get those bass tones.  Super glad I went with the s-type, it's loudest at a could start, low/soft growl with driving in lower gears around town/in neighborhood, at highway speeds you can't really tell it's there, until you press on the gas to accelerate or pass someone.  I'm in my late 30's and didn't want to go all high school on the exhaust, but super happy I went with the s-type the deep tones are nice and rich, and should really mellow out over time, and it's not obnoxiously loud.  And absolutely zero drone at highway speeds.

 

 

 

 

 

What part of Houston are you in? I'd like to hear the S Type in person (if youre cool with that)

 

Ive driven the Touring (GMPP on an AT4). Trying to see if the S is "too loud"

      2026 DENALI 6.2L

      By pyoung62 · Posted

      I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.

      Can you add a 360° Cameras hard button to a 2021 Sierra?

      By ShowMeShooter1332 · Posted

      I am curious if anyone has figured out a way to add an hard button AUX or 360 Camera switch to the center row of switches. I have a 2021 AT4, and want to split the hill decent button and add a 360 camera button so that you don't have to go into the center display and locate the camera functionality, etc...   My father's 2024 Yukon XL AT4 and it has a hard button, see below. I found this thread on the Yukons, but it seems like there may not be a part number for the 2021 sierras. https://www.gm-trucks.com/forums/topic/255339-adding-hard-button-for-camera-on-2021/ Anyone else figured this out. Seems like it would need to be a custom switch!   I am getting ready to install the auto stop/start eliminator, so would be nice to knock them out at once.     Upvote1Downvote0Go to comments

      Oil Consumption

      By Chuck FB · Posted

      Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.
