I wouldn't remove the middle muffler. Generally that is your main largest one. Remove the front one. If it's still not loud enough, then replace the rear resinator with a hot dog. If it's still not lound enough (or was no where near loud enough after removal of the front muffler), then just remove the rear resinator altogether (replace with pipe).
As for droning with no resinator, if you want your exhaust that loud then the droning is unlikely to bother you at all.

i dont want it really loud, where you can hear it blocks away. just a little louder than what it is now. so removing the rear muffler should do that wouldnt it? so ill have resi, then middle muffler, then straight all the way to the tip

I'd remove the first resinator, and leave the one in the tailpipe personally.

i have motivator extractors (old pacies) a muffler, a hot dog & a res, all through 2.5"

i was told i had to get the res put in for blue slip because it was a touch too loud & that was a pretty lenient blue slip (won't go into detail )

at first i didn't like the resi in but it makes the need for me to keep panadol in the glove box on long trips obsolete...
