so I've recently done 4.56 gears, I currently have 295/70r17 tires, but moving to 35s around Christmas, I do a bit of Highway driving about 200mi a week give or take, my mbrp cat back makes too much noise, since I'm sitting at 2200 rpm at 70mph. Now I'd imagine I might drop to 2000-2100rpm when I make the jump to 35s, but that won't make me that much quieter.

I have a predicament because eventually I'm going to do LT headers too, but they will be wrapped for noise and engine bay heat. I will also be keeping or replacing my cats.

So my question is kind of a two parter, what quiet mufflers are you guys using? Dynomax super turbo? Hush thrush? Flow master 70series? Walker sound fx?
I'm thinking of just getting a regular old walker muffler and dumping it for now, eventually running it out the back when I do the headers

What's yalls thoughts?

Drone in these trucks is not fun. I really like my Dynomax Super Turbo, great tone and minimal drone. It only drones if I hit that sweet spot towing up a long hill.

I went with a dumped(I know not good for cabin noise, but cost effective for now) Thrush Hush 17635
(I think that's the part#) almost no sound on the highway now, nice and deep, deeper than my mbrp.

I have the flow master cat back and that's really quiet. I need to open the windows if I want to enjoy the sound of it

If you go Walker, get the Stainless Steel. I had a a regular 3" aluminized Walker Sound FX on my lifted V8 Jeep WJ. It rusted out in 10 months. Sounded good (quiet) before it fell apart.

Im looking at these for mine: with a straight through SS magnaflow knock-off for $194 shipped

Or just the knock-off SS (Max-Flow) MF2259 muffler for $45 shipped.

I'm going back stock to fit my sleeper theme. My setup goes as 4.56 gears, lq9 6.0 **, 4l80e (spins more), 3200 circle d(likes revs), long tube headers with off road wye!, iirc 22" magnaflow straight through design.

Truck is way too loud even being reserved. Highway I stay around 2500 depending on what speed I cruise.

Plan to replace magma flow with stock muffler and add a resonator off a 2016 truck to the near end of the tailpipe which is also dumped under the truck....

When I add a blower it should still be quiet with that setup

Yes I did. My original swap used the relay method then I got my computer segment swapped and got rid of the relays. That's when the truck really drove like a heavy duty truck like it should. The shift patterns where better.

Went with Corsa. Also Changed Cold Air Intake to Voltech. Coolest set-up I have seen, it's a sealed system with forced air scoop. Voltech.com. Magnaflow could not shut it up.
