The helicopter sound is from the AFM/DFM/DOD whichever one your vehicle has, it s when the cylinders are changing from 8 to 4. Gotta delete the active/dynamic fuel management and it will be 8 cylinders all the time and no matter the muffler you won't get helicopter sound.
The magnaflow actual sounds great on the 18 model 6.2 without the resonator. Single in dual out. No drone and when you step on it its a nice deep rumble.
The Super 44 is the best out of all of them but out of the new body style trucks that have a completely different exhaust setup from the factory, I think the muffler delete is the best.
Thank you so much for this video! I just bought at 2021 Chevy Trail Boss and I am looking for a better sound, it is too quiet for me. I am going to go with the Flowmaster Super 10 Awesome Video!!
Definitely the atak or flow force 10. How are either with drone? I love your vids and setup, no extras, no wasting time, just the facts…I love it! I’m still leaning to the corsa touring from your other video…
Helicopter noise is caused by Active Fuel Management not the transmission it doesn’t matter if it’s a 4spd 6, 8 or 10 AFM makes aftermarket exhaust sound weird
Flow master 50 series delta flow, put one on my 6.4 liter 2500. Hardly any drone, deep rubble when your accelerate smoothly. Roars when you step on the gas lol. Love it, barely any drone in the cab.
Thank you for this video. I have a 6.2 so this helps, somewhat... I would have like to see the DB meter before and after the install. Only because I'm sure it sounds different in real life.
I had the super 10 dumped off under my back seat and couldn’t hear myself think. When getting up to speed on the highway. Literally had to wait until I was at highway speed to talk to the person in the passenger seat. That was with an 08 5.3L lol
Is it safe for the vehicle to go with a muffler delete and straight pipe? My truck is too new to harm anything on it if you know what i mean lol. Oh and also do the muffler delete require much work?
If anyone out there is getting the "helicopter" noise with a 19-22 5.3 or 6.2 I would invest in a Pulsar LT. You can disable DFM/AFM and keep it in V8 mode at all times. It also prevents your exhaust/muffler from sounding like a ricer. Plus it can deactivate auto start/stop. It's a great investment. I actually gained MPG turning off DFM/AFM on my 21 6.2 trail boss. I put on a Carven TR on kept the resonators on and no issues.
My thoughts...1st truck... Dude talking in the video: "Its about 20% louder than stock" lol ME: More like 2%! Still better flow than stock though for sure.
First one is way too quiet. I personally don't understand the point in paying for an exhaust system if it's just as quiet or perhaps even quieter than stock. The performance and fuel economy benefits for any exhaust system is negligible at best and don't really ever show up until you get headers and a tune. Just stick with the stock exhaust if you don't want something that you can actually hear. Definitely a well made exhaust system but still, kind of pointless since it's so quiet.
I'm looking for advice from somebody with the same experience as me. I have a 2021 Silverado with a 6.2l. it came with a single flapper valve. I installed a Magnaflow direct replacement 3.5" muffler delete pipe. It sounds awesome from outside but not so much from inside. The drone at 1,500, which it cruising speed, just sucks. I want as close as I can get to the beat of both worlds, loud, nasty and throaty without drone. Any recommendations for a muffler? Otherwise, I may have to pop to the Borla cat back dual touring
for the guys that do the muffler delete but leave the resinators in, it makes me wonder how it would sound if the removed the resinators and put in a pair of super 10s, how much different would that sound vs someone that replaced the muffler with a super 10 and removed the resinators
Guys I need help.... I just bought a 17 Sierra with the 6.2 ..... I dont know anything about mufflers or exhausts..... but the local exhaust shop I called recommend the flow master 44 or super 10 .... any recommendations?
I think they sound good. A lot of people just want a deeper sound and don’t need to annoy the entire neighborhood. Did it in highschool. Don’t need that anymore.
wow... this guy wanted to trade me his borla exhaust for my stock exhaust.... after hearing that weak ass exhaust, i'm going corsa. there's no comparison.
At4 with what?v4 v5 vwhatever....those trucks are such crap.pay money 4 quiter than stock.Junk piles that will leave you when ya need em most.Take that truck to Kenny Rogers Roasters for the exhaust.
Something tells me that first guy will be back
No doubt
Definitely
I want to hear with the resonators off
Lol right trash... inside you hear absolutely nothing.
Yea he just didn't fit it 😂
Honestly I think the Flomaster 44 had the best sound, would’ve liked to have heard it on an AT4
It’s the same 6.2 unless it’s diesel
It's the same motor, only difference is the package (trim level) a 6.2 in a Denali is the same as the at4
The helicopter sound is from the AFM/DFM/DOD whichever one your vehicle has, it s when the cylinders are changing from 8 to 4. Gotta delete the active/dynamic fuel management and it will be 8 cylinders all the time and no matter the muffler you won't get helicopter sound.
Needs to get a Pulsar LT and delete it.
Flowmaster delta flow 40 series sounds the best for me. No drone, not aggressively loud during driving, idling sounds awsome!
The magnaflow actual sounds great on the 18 model 6.2 without the resonator. Single in dual out. No drone and when you step on it its a nice deep rumble.
I think I’m going with the muffler delete 👍

ALWAYS BEEN A FAN OF SUPER 44.. ALWAYS WILL BE... NEVER DISSAPOINTS.
Definitely the atak or flow force 10. How are either with drone? I love your vids and setup, no extras, no wasting time, just the facts…I love it! I’m still leaning to the corsa touring from your other video…

The first gmc guy needs to cut the resonators. The magma flow is already literally a giant resonater
I personally like corsa sport exhaust!! Zero cab drone and nice sound. I believe gains 13hp & 10ish torque.
Thank you for this video. I have a 6.2 so this helps, somewhat... I would have like to see the DB meter before and after the install. Only because I'm sure it sounds different in real life.
In my honest opinion with the 6.2l, the Corsa Sport Cat back sounds the best. For a catback system they flow and sound amazing.
borla FTW!!
I had the super 10 dumped off under my back seat and couldn’t hear myself think. When getting up to speed on the highway. Literally had to wait until I was at highway speed to talk to the person in the passenger seat. That was with an 08 5.3L lol
What part number on the Flowmaster Super 10 did you use?
Is it safe for the vehicle to go with a muffler delete and straight pipe? My truck is too new to harm anything on it if you know what i mean lol. Oh and also do the muffler delete require much work?
that 1st one. Ditch the mid muffler and do 2 Flowmaster outlaws where the resonators are
The original flowmaster 40 series with no resonators at the back is what y’all want.
Love the details, good research for builders and warriors alike. 🙌
I took your advice and went true dual, there’s no other options!
Ok
If anyone out there is getting the "helicopter" noise with a 19-22 5.3 or 6.2 I would invest in a Pulsar LT. You can disable DFM/AFM and keep it in V8 mode at all times.

how did you do it
Mine did the same cause of afm it goes into v4 mode and it sounds like shit with a aftermarket exhaust I have mine deleted with a range afm disabler
#4 sounded the best🤌🏽
My thoughts...1st truck...
Dude talking in the video: "Its about 20% louder than stock" lol
ME: More like 2%!
Still better flow than stock though for sure.
What's better straight out the back or the sides
Damn too bad you guys aren't out here in SD,Cali. Man I would really love to have you guys do the exhaust on my 07 Yukon Nali
Just plug in a RANGE TECHNOLOGY afm delete. Install Borla Atak or Corsa 😉
Did that on my 2017 yukon different truck
1st guy: yeah boi!!!!
Everyone and their mom: sounds.......stock......
How much money are the cats worth? That way when i get my exhaust i have the muffler guy deduct it from my bill!
you get my approval
Thanks for the videos!
Thank you for watching!

I like the 44 best, but would have liked the 10 without resonators
The best is Corsa exhaust no drone on inside but load outside

Borla attak or corsa is your only alternative.
@@exhaustaddicts Do you think the Attak will kill the drone?
@@tombanse5450 IMHO Corsa is the way to go. They cut the drone totally. ATAK sounds great too though, you can't go wrong either way.
You guys know anything about the cherry bomb extreme mufflers? If there loud at all? I've been trying to find something about them.
We got a few videos on them. Good mufflers and give a nice tone
The helicopter sound I believe has to do with AFM when it goes from V4 to V8
for the guys that do the muffler delete but leave the resinators in, it makes me wonder how it would sound if the removed the resinators and put in a pair of super 10s, how much different would that sound vs someone that replaced the muffler with a super 10 and removed the resinators
A super 10 without resonators will sound like sex but also drone and give you tinnitus
last one for me, Flowmaster!
44 is the best
I had a magnaflow cat back system on my 5.3 6 speed transmission and it sounded nothing like that.
Because it was a gutless 5.3
Guys I need help.... I just bought a 17 Sierra with the 6.2 ..... I dont know anything about mufflers or exhausts..... but the local exhaust shop I called recommend the flow master 44 or super 10 .... any recommendations?
Depends on the tone you want
I've always run super 44 on my trucks. Perfect tone and aggressive but nit obnoxiously loud
May I ask what equipment did you shoot with?
a phone!
I could barely hear it. I think those Magnaflow are not worth it if you wanted a deeper sound. Flow series 10 sounds awesome.
How do you get rid of the drone affect?
Keeping your resonator on.
Buying a Borla atak and leaving the resonators on..... rediculous.
The second one has a weird vibration that sounds like a phone ringing.
Do any of these improve gas mileage?
I'd be okay knowing if any just don't decrease it, i doubt you'd get "better"
Does a exhaust tip on a stock exhaust make it sound better?
No
Strictly aesthetic.
Nothing like paying to have a stock sound
Ok.. so my muffler shop guy calls the mid muffler a resonator and tells me the mufflers are those two resonators. Which is it?
Resonator is after the cat, those ones at the back are mufflers.
Super 44 was nice tone not raspy Decent
Why does my at4 sound louder with the gm performance package?🤷🏽♂️
It's probably the audio quality of this video because I believe GM uses borla for their exhaust systems.
Muffler delete and he kept the resonators? What a Nancy
they never listen to leave atleast 1 flapper on
AWE Cat back
It's because you cut the valves out.. should have left them in.
Those guys need to delete AFM if they want it to sound good, that kills those trucks anyways
Corsa > All
15 MPG
The first truck just sounds stock 🤦♂️
They all sound quiet tbh
I think they sound good. A lot of people just want a deeper sound and don’t need to annoy the entire neighborhood. Did it in highschool. Don’t need that anymore.
I really like corsa. Corsa is nasty
The Flowmasters on the 5.3l sounded better than these
Terrible with that 22 in. Magnaflow and factory resonators. He should have gone with a 14 in. Magnaflow.
wow... this guy wanted to trade me his borla exhaust for my stock exhaust.... after hearing that weak ass exhaust, i'm going corsa. there's no comparison.
terrible background noise interference, Sorry
The first one was awful! It's the stock one basically
Very quiet
At4 with what?v4 v5 vwhatever....those trucks are such crap.pay money 4 quiter than stock.Junk piles that will leave you when ya need em most.Take that truck to Kenny Rogers Roasters for the exhaust.
Ummmmmmm WHAT?
Funny I've never had any of my gmc leave me stranded ,always taken whatever I've thrown at them
Hahahahaha to quiet waste of money!
It’s not worth it putting a muffler on a GMC 😂😂😂👎🏼
What?
