Go to youtube and listen til you find the sound you want.
The hard part is finding another vehicle with the sound you want in real life,
and then realizing you want to sound like someone else.

I spend countless hours on YouTube, nothing comes close to my liking.
Maybe magnaflow 12589 swap , or flowmaster Force II , because i can have it for same price
I commute 100 miles daily on the highway, doing 70-80-90 , i need something not to obnoxious.

If they don't come close to your liking, the price ain't right. You'll regret spending that money.
Although I'll suggest that the exhaust you get should not have less acoustic chambers than your GM OE.

Might be better off getting a tune ...

your not going to get that sound out of a gm, but the carven systems probably sound the best, they make different sizes so you would have to poke around and see which one is not going to drone

I run a 3" Flowmaster pro series and it keeps volume very manageable at partial throttle and pretty rowdy wide open. I have a 6.2 with long tubes and cats, for reference

 

[Samuraj]

I think , I’ll stay with stock for a while , until something real mellow came to market

But it sounds so good lol Goodluck on your search , let us know what you find

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 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
