Really can't blame any of the guys and their exhausts. GM went out of their way to really quiet the 6.2 for this generation. My gut tells me their DFM(skip fire spark system) may have something to do with it. Then who knows how restrictive those stock cats are. These are nothing like the old LS-based 6.2s.

[@alva1370]

Flow FX wins this one, 40 series is a close second. I like quiet so the Magneflow is a different kind of win. 70 series are quiet and sound great driving away too. The black tips are perfect.

[@jesusbalderas839]

This guy went through 3 mufflers and it still sounds close to stock. Honestly if your so picky about drone don't bother upgrading your exhaust.

[@hdrolling]

It's different trucks, one has black tips on the carbon edition and one has chrome.

[@trollpatrol3930]

Or get the real deal. These guys here are the bomb! kzbin.info/www/bejne/aGW2fWqElJ2qo7s

[@Reny.Rosales]

Love all your videos man! All this info and sounds clips help in making decisions!

[@robertophillips9545]

Thanks for the great video and advice Wally. Been driving for a week with the new Magnaflow and it’s great. Thanks

[@robertophillips9545]

@Don Quixote Magnaflow 12909. Body length 22inchs. Overall 28 inch’s

[@robertophillips9545]

@Don Quixote just learned about this disabler on Holly.com doing research. But the muffler worked well. Very low drone in 4 cylinder mode will get the disabler and try it.

[@joshhibschman]

Right at 6:39 and part of 6:40 you can hear a very high pitched tinny squeak/chirp coming from the passenger-side cat. It's common on the GMC 6.2L at 1200RPM when the cats are cool enough (cold start or cruise at 40mph). Wonder if its from weird pulse turbulence from the crossover pipe. Ever noticed it, tried solving it?

Hello, I had a Cherry Bomb Salute offset / center SA2589 5x11x22 put on my 2023 GMC Sierrra 6.2L. I think it is to loud. Would the Magnaflow 12909 be quieter? Is the Magnaflow a better muffler. Thanks a lot for the info. Luv your channel

[@kennyjackson5296]

2020 man, everything's quiet anymore

[@KrishMod520]

I think the sound decibels were high because of all the traffic noise in the background 🤣🤣

[@kodybryantmusic7357]

best muffler for the 15 silverado, if I leave everything else on? want a louder note, but deep rumble, not aggressive note

[@Bandit77TA]

I had to keep turning the volume up. That thing is quiet!

[@mykecollins3255]

3 of the quietest vehicles thats been on this channel...still giving thumbs up,but not for the trucks.

[@ginorogers5668]

MY BROTHER HAS THE SAME TRUCK AND U NEED NOT TO BE CHEAP HE WENT WITH CORSA EXHAUST THE ONLY WAY TO GET THAT SOUND U WANT

[@russschwerma1246]

How long do magnaflow mufflers usually last as far as the fiberglass packing material burning out?

[@ethannthomasonn]

Was that the same guy for all three mufflers?😂😂

[@TheUndertoe]

No

[@ff912]

Those resonators need to go.

[@martinlopez9096]

Got a 2019 AT4 what’s a good exhaust something not to loud but sound like a man’s truck

[@mytriton54]

Magnaflow all day long.

[@user-zx2xx9oc4h]

I've been wondering for years, what is your accent?

[@TheHaylock12]

On these he only rapped it out to 3 k rpm last videos he was over 4 wonder it’s not as loud interesting newer trucks to maybe that’s why

[@guadalupenovelo4304]

💕 saludos

[@dodson777]

Where is this shop located?!

[@exhaustaddicts]

[@brianpennington2018]

I thought Flowmasters were American made not made in China.

[@jaydoublebusy]

[@anthonyzanni3360]

[@russbrittain410]

Magnaflow sucks hate there mufflers no sound what so ever

[@seymourbutts8850]

He keeps saying no drone on the FX. That's completely false. The drone is terrible.
