Has anyone done anything to quite down their car? I removed the cats and now my car has this drone to it. It's partly because it's a stalled auto so when cruising the rpm stays about the same while shifting thru the gears under light throttle.

I know many ppl put resonators in the intermediate pipe - may be worth doing

I'm wondering about a small (short) muffler or resonator after the turbo

i run a dynomax bullet muffler and a borla 3.5" intercooled tip after the turbo. It took away all the rasp and sounds MUCH better now

I currently have a Borla XR-1 oval, per the recommendation of a tuner. I don't like the way it fits (it is too wide) and would not recommend it to anyone else. But I did like the sound a lot better.
I have a Moroso spiral flow sitting in the box which will be installed asa the new engine is installed. I am certain it will sound worlds better than the stock STS no-muffler approach. Will put a Borla turndown tip on it asa it is available from Summit.
