This was what i was going for. Tried the quietest flowmaster and borla touring but at highway speeds still too loud. Currently have stock muffler but removed the resonator and flapper valve and added a K&N Cold air intake. Now it's perfect for what i was looking for. It's weird to think the intake/throttle body sounds kind of like exhaust noise but it does. Plus super quiet when cruising but a nice smooth sounding amount of extra noise when stepping on it. Cold starts sound decent now too.

I’m searching for cat back or muffler swap , aiming for stock SRT / AMG sound
2019 Tahoe 5.3
I have good deal on flowmaster Force II , but I’m not sure ……

I would go with whatever is less noisy. People hate noisy cars.

How is the success rate with 18” magnaflow? 12259 to be specific.
With stock resonator

I've got this system on my truck as well. BTR Stage 1, so less lope and no headers...mine is a tad quieter.
The thing I like about the Corsa set up is it's barely there when you are cruising. Honestly not sure how they made a system that snarls when you hit the go pedal and yet is hardly audible going 80 mph on the open road.
Love the cold start snarl as well while it's settles down to desired idle.

FWIW, a Dynomax turbo muffler scored high on an episode of Engine Masters for being quiet and costing little power.

Dynomax is recommended by AI when you google search
