You need to hear any proposed exhaust system from inside the car for several miles. A loud car is not pleasant to drive.
A muffler delete will indisputably be louder than any aftermarket exhaust and the popular Invidia Q300 was actually painful on my car (and my buddy's). The Q300 is claimed to be "not that loud" by many here.
The Invidia N1 is noted to be louder. And these both have mufflers.
My system (see my earlier note) dynos at 221bhp at the wheels on a conservative Mustang dyno. With a Gernby FlashPro road tune. You're unlikely to exceed that power by taking the mufflers off and/or letting the OEM ECU try to manage things. Note the OEM exhaust if\s very heavy. Significant power is only gained by forced induction. Note when introduced the S2000 engine had the highest power to displacement ratio of any normally aspirated engine.

I have heard youtube video with back to back uk mod and muffler delete. And at least on the video, the muffler delete just sounded like an amplified uk mod (compared to 48 mm uk pipe). But, it is my understanding that car I heard still had a cat. Combining muffler delete and tp sounds like (pun intended) a recipe for rasp and hearing loss. However I admit I've not actually heard, live nor audio, this combo.
Go with a big uk pipe, then if that is not loud enough, add tp. If still not loud enough, muffler delete (then all you've lost is cost of uk mod). If now too loud, put cat back on (then sell the tp).
Most cost effective way to go about this without making a choice you will regret.
Oh, if looking for aurial intoxication, someone mentioned adding an intake for sound. That would certainly augment what we think you're looking for. But if you want to accomplish something similar on a budget, or simply want to avoid some of the compromises some intakes can have (less effective filtering, ricer look under hood, hydrolock, etc), modifying stock airbox is possible. One popular way is cut a 3" hole in the passenger side, and duct a flex intake hose from adjacent fender opening to the airbox. You are piping colder air, added sound, and no risk of hydrolock. Try driving with airbox lid removed for a taste of what that will sound like. Not that lid off will be considerably louder than just adding a hole, but its similar sound, just not as loud.
Inconjunction with this, usually the airbox resonator hole is plugged, and portion of interior airbox wall removed (leave a little wall to prevent possibility of hydrolock), and lids air guides removed.
Its virtually free, and makes a nice improvement in sound without sounding obnoxious.

When I changed my exhaust I couldn't get the bolts out for several hours. I took the car to a muffler shop and they loosened the three bolts with a torch for me and then I drove home. It was loud as hell.
