what do you reckon with removing mufflers ???

the old folk who had my falcon before me had a full cat back 2 1/2" zost fitted but it has 2 centre silencers(mufflers) and one bigger under rear at tail pipe...
now, its too quiet in my opinion and i want to release some sound...not a deafening racket but a nice growl....so, who or where should i take it to get modified and are there any issues with cops etc ?
i dont want it to sound like a hoons banger !
anyone near redcliffe area that can be trusted with a nice car (and can do a nice /neat job) would be appreciated...oh and a rough guess to price ?
