Top 4 BEST Exhaust Set Ups for GMC Sierra Denali 6.2L V8

[@timothymacdonald4793]

I have the 2017 Denali with 6.2 and I've always been a Flowmaster guy....but. I had an 18" Magnaflow put on with dual exits, had the stupid flappers and resonators taken off and it's freaking awesome. Nice deep rumble on cold start, sounds great running through the gears and no drone on the highway! Everyone has a preference and this is my new one.

[@derekchauvinisahero2010]

Magnaflow is a much superior product

[@johnmflores85]

Dude that first truck sounds sooo fn sweet. I wanna do it to my high country

[@TimFletcher-jn4or]

How did your High Country turn out? Did you get the same results?

[@johnmflores85]

@@TimFletcher-jn4or i actually did get it and i like it. The truck is too quiet without anything. Before i got it i was driving through a parking lot and some guy wasn't paying attention and walked right into my truck but now it's not obnoxious but definitely noticeable

[@TimFletcher-jn4or]

John, thank you for replying! I wonder if my 6.2l Yukon would sound the same? I have a single exhaust tube but I also do not want it too loud and obnoxious. I really like the sound of the second truck in this video. Maybe I will go to a local exhaust shop and show the video and explain what I am trying to achieve. I hope there wasn’t any damage to your truck and that guy didn’t get hurt in the parking lot. I can’t believe how much people don’t pay attention to the world around them! Best of luck with your truck, and thank you again!

[@TimFletcher-jn4or]

John, do you have a sound clip or video you could post with your truck?

I love these comparison videos! So damn good

[@blackhurst25]

I put the super 10 Flowmaster on my 2020 6.2 10 speed. The sound at start up is great but the intererior drone is way more than I expected. I left the resonators and removed both flappers. Flowmaster recommends a multi chamber 50 series muffler to get rid of the drone but I was worried that would be too quiet.

[@everettcabalar8416]

Got mines with the performance package. It’s perfect when you get on the gas but just the right amount of rumble when cruising.

[@kyleerickson3382]

any drone at 70 to 80mph

[@everettcabalar8416]

[@markbucher6928]

I have a 2022 Silverado trail boss with 6.2l. I went with the super 10 and kept the resonators. It sounds perfect to me.

[@OddTimeMan]

Why in the world would the guy with the silver Silverado go with headers, high-flow cats, and then bottleneck the exhaust with a Y-pipe into a single tailpipe? That defeats the purpose!

[@justinnassef8112]

That’s what I’m thinking smh , that’s like wiping before you poop .....

[@theozman38]

Justin Nassef ha ha haaaaa !!

[@offroadcrazy]

Mine is that way and it's a hell of a sound.

[@Maverick09171]

A single 3” pipe can handle a ton of flow. Like 700hp. There’s no bottleneck in that truck

#2 is the best

[@jamesgang94591]

The last truck almost had it. Gotta get rid of the resonators. Don't waste money putting on an aftermarket muffler if you're going to leave them on. If you want to leave the resonators on, you might as well go without a muffer and save yourself $100.

[@DragonKnightX12]

Not everyone wants it super loud though. Would be nice if someone would make a good valved exhaust for the trucks.

[@mikecastleberry9671]

True duals x pipe a leave just resegranaters only no flapper valves quad black tips for looks good sound and most of all performance 😊

Ima need those headers and exhaust for when i get a truck because that sounds amazing i need more information on what you guy did to it

[@TimFletcher-jn4or]

@exhaustaddicts - I have a 20 Yukon Denali 6.2l. I’m looking at the Flowmaster 50 Series BB or the 70 Series BB. I really like the sound of the second truck, just a nice deep rich tone and not loud. Will I get that similar sound with either of the two I’m looking towards? Thank you for you inputs!

[@99hawk75]

they all sound great! Id like to know what the drone is like at highway speeds myself. they all sound awesome though!

[@RoadWarrior77]

That Super 10 didn't sound too bad.

[@turnerc23]

What was the decibel reading on the flowfx?

[@1maxsor1]

Ive always thought the exhaust systems of cars were Cats -> resonators -> mufflers -> outside Resonators are for drone and mufflers would be for loudness. My 2016 Altima 3.5SR its a catback straight back and highway sucks. I shouldve kept my resonators for drone

[@johnmflores85]

Would the sound change if you kept the back flap and deleted the front?

[@dennistv598]

The flaps is there to restrict the flow I believe u delete it to make the flow faster i maybe wrong tbh I’ll do my research

[@misael008]

Kinda like the first one more, i wonder how it would sound without the flap and resonators 🤔

[@thunderbolt5354]

@ Exaust Addicts No Exhaust system Compares to Corsa ! Best aftermarket exhaust on the market !

Which muffler for best deep tone and loud? Currently have a black widow venom 250 in my 2019 5.3L Silverado with flap cut out and resonator holes covered. Thinking about what to put in my 2020 6.2L. I like the tone of the venom 250, just wish it was a hair louder. You ever use this muffler?

[@dennistv598]

I would get super 10s

[@dennistv598]

I have them on my tundra sounds like a beast when fully warmed up theres a lot of drone at 70 mph but it isn’t that bad

[@SassyEmotions]

Black Widows widowmakers would give you the deep sound you're looking for. Had them on my '17 GMC with the 6.2l (true duels)

[@andresfonseca5475]

When you get longtube headers installed does that cause the engine light to light up ?

You have to use green cat built in the hole system cost. 2000.00 but you gain hp you can calm it down with x pipes and resignaters and quads 4 tips sound and performance 😮

Super 10 or a black widow

[@ej1025]

Carven TR and Borla XR-1, real deep with good tone.

[@OddTimeMan]

Don't just consider sound, consider exhaust flow too. Chambered and baffled mufflers don't flow as well as straight-through mufflers. Dual exhaust flows better than single exhaust. Removing restrictions improves exhaust flow.

[@desmondfitzpatrick4950]

Did you ever pick an exhaust yet? I have a 16 and was wondering what to get as well.

[@72gunslinger]

do a video in cab on the highway at 70+ when the trucks are in 4 cylinder mode to see how bad the drone is

[@aydenpals9403]

The best exhaust hands down is leave the two converters that are at the header, and do a single straight pipe all the way back. Cost me $150 and sounds better than every exhaust out there.
