I ran a 5x11 14" magnaflow in place of the stock muffler this weekend with no cats and stock manifolds. It sounded great, but drone at 1800-2000 was unbearable even with the windows down.
I get headaches easy, so i need it quiet like stock.
Im gonna order 2 more magnaflows and give them a try, maybe a 22" 5x11 and a 30" 6" round muffler. And if i have room, ill add this 14" 5x11.
We shall see how quiet it can be. And im sure the turbo will kill a good bit of noise. I know my STS with that 14" magnaflow was pretty quiet.

I've switched up exhaust a million times, and now I've got a smaller Magnaflow, so I know how bad it drones. But, I've found it to work better with the bullet(s) before the larger (oval) case muffler, if you're wanting to deaden noise/drone. Resonators are behind the mufflers in a lot of OEM applications, but as far as aftermarket goes, I like a properly-sized bullet in-line, in front of a larger case muffler. Seems to work for the whole quiet deal.

Regarding the DB Black muffler, When I stomp on the gas, I have had several people say my truck sounds like a stock car when I was half a mile away. I just laughed and said its not that loud. I guess it's pretty loud to most people though, but in the cab if windows are rolled up its not loud at all in the truck.

Is it the actual sound from oustide your truck that keeps you from being able to talk on the cell or is it the drone in the cab? I am going to have a funky looking exhause setup later this summer. Lt' 3" pipe to Magnaflow X to 2 4x8x16 bassani's and have 2 drone tubes put in to move the drone to a higher RPM to overcome the in cab noise issue.

Also the longer the tail pipe the quieter it would be. Go with the biggest muffler you can fit, mount it as close to the engine as you can. You could also run a bigger diameter pipe then needed and run an extra muffler. Would still flow but keeps it quiet. Old hot rodders trick my grandpa taught me, when they didnt want to attract attention from the cops when they raced

Just make sure you get the biggest O.D. bullet you can find, or one close to it. Regardless, I'd bet it would turn out stupid quiet.
