You need to cover up the mesh screens between the exhaust tips and Y-pipe. They're near the spare tire and they cancel out a LOT of each muffler's exhaust note. That's why all these mufflers sound so quiet.
@@FMSPerformance how much of a difference did it make? I really like the super 10. I had the 40 series on my 18 which was decent but I want a little louder. Just dont want it too loud as I have the kids in the backseat ( and dont want to piss the neighbors off)
I run a 3 inch cat back, exhaust flapper valve delete, flowmaster super 40, single side exit. Sounds really good. Nice and deep and mellow. No Hwy drone either. Get a tuner as well, get rid of the v4 mode, lets the engine run so much better.

Awesome video, the first flowmaster 40 series sounded best in my opinion. The borla sounds more like an import exhaust. Everybody has different tastes though.

This was useful. Wanting to just swap out muffler in my 2022. Looking for the best one to get with a good tone and not crazy drone. Just little aggressive when I get on it. Nothing to crazy. Thanks for the post
I've had the straight pipe for about 6 months now on 2019 Sierra 5.3. Love the aggressive sound but have found out that when cruising to stop or down hill under 10mph it has a horrendous loud popping sound. I'm also getting tired of the drone inside at highway speeds. Watched this video to see which muffler to go with now. The atak sounds just like the straight pipe and hopefully eliminates that popping crackling but is it worth the extra cash?

I like my Flowmaster super 44 muffler on my Silverado. Sounds clean deep tone and not too much drone in the cab. Everyone that is looking a an exhaust system for there truck/car, try out the super 44 by Flowmaster
Gen 3 vortec sounds good with flowmaster 10 but with this motor... I don’t know why but on the throttle down I hear what sounds like vibration. It’s prolly rasp but (flame suit on) I like fords 5.0 sound better

So do I just buy the Borla Atak exhaust or do I need to buy anything else to make it sound this good?
The Borla Atak exhaust kit sounds nothing like this. We just replaced the muffler only with the Borla create Atak muffler. For more information about this muffler follow the link below.

Nice video! Which one was the quietest?
Thanks for the comment. I think the Magnaflow was the quietest. Please subscribe for more updates. Thank you.
Is the exhaust flapper necessary? I just got a super 10 and I saw the flapper on my original exhaust would it cause any problem with out it?
I’m assuming you are just doing muffler swaps and not the entire exhaust system?
Yes, on this truck it was just the muffler swap. The OE tail pipes with resonators remained. Please subscribe for more updates, thank you.
Stupid question I’m sure everyone asks.. hard to tell from the video, but what would u recommend for a nice clean throaty sound, but not one that will make the neighbors hate me or hate myself when I’m driving down the freeway at 70mph?
Flowmaster Super 10 was our favorite. Thank you.
Was this only swapping out the mufflers? Resonators and rest of exhaust was untouched?
Yes, we removed the muffler and exhaust valve only. Thanks for contacting us, please subscribe for more updates.
Whatever muffler you pick, that flapper valve has to be deleted.
It doesn't have to be removed but we did and recommend removing when you change the muffler. Thank you. Please subscribe foe more updates.
ATAK
Thank you
Needed cherry bomb glass packs
These all sound like the resonators are still there...why?
Good ear. Yes they are. We wanted to hear what it would sound like with just the mufflers changed with the factory tailpipes. Please subscribe for more updates. Thank you
Which is the cheapest you would say
Straight pipe or the Flowmaster Super 10

Nice 👍🏽
I contacted Borla they said they don't have a ATAK for the 19-21 5.3L yet here it is... How do I get this lol is it technically for the 6.2L?
Thanks for contacting. This is a custom exhaust using many different universal mufflers by the manufacturers. We did not change the piping just the muffler and eliminate the flap valves.
