It will make the drone worse. I run a straight-through muffler on mine.

I have a silverline 4" turboback. Installed all of it went for a ride and took the muffler off and straight piped it. Its not really loud in the truck and you can really hear the turbo whistle

I personally think that quick revs sound like S**T on a straight pipe, but screaming down the road is nice.

3" DP to 5" side dump straight pipe here. I really like the raw sound of the straight pipe but it's a lot different than the deeper toned rumble of a hiflow muffler. Either way is cool and I don't think the straight pipe is really any louder, just a way different sound. I don't find the drone bad at all. My CAI (afe II) makes WAYYYYYYYYYYYYY more drone and cab noise than the pipe.

Which one sounds better?

The straight piped trucks sound raspy and rough.

That's a straight piped IDI vs a muffled 6.0 :

Seth your truck wont sound remotely close to either one of those (muffled or piped for that matter) and comparing the sound of an IDI to a 6.0 is like comparing apples to oranges. The 7.3 DI PSD is somewhere between those sounds. I wouldn't base my decision on that video one bit.
