3.0 Muffler Delete - anyone done it?

[Fifty150hs]

Guys: been searching the board to get info on muffler delete for my 3.0. I'd like a little more aggressive sound. I had the exhaust disconnected from behind the center resonator when I changes my diff bushings. I fired it up to see what it sounded like and it sounded pretty good, but it was also pretty "droney". Anyone done this mod? I'm wondering if the droning was a function of not having pipe all the way to the rear or if it is likely to drone even with pipe all the way back. Maybe a glass pack in place of the muffler would cut the drone?

Almost all of the posts on here are for V8's so, they're not much help.

Any ideas?

Thanks!
