I really don't know how the Magnaflow will sound.

We use the magnaflow 12267 (12265 would be the 2.5" equivalent) for our quiet budget option WRX & STi Hatchback exhaust designs. It is EXTREMELY capable of keeping noise down but still has a pretty nice tone to it vs. the factory baffled muffler.
One note, it's 409 stainless steel, so it will have more of a potential to rust over time, especially with you being around salt air down there near the ocean. One option to avoid that is to simply grab some good stove paint in charcoal black and paint the muffler entirely up to where the inlet/outlets are welded into it.
I'd not run a resonator to start with if you run that 12265 and then add one if you think it is too loud, but I doubt you'll find that. Because there is so much interaction with the acoustic waves inside perforated Y in the Magnaflow muffler, there is almost no difference in adding vs. eliminating the resonator. Certainly no need to control drone or anything offensive.
Good luck! I'd be curious to hear what you're being quoted. There are a lot of great exhaust shops that do top notch TIG work out there, but all in all you will usually end up spending the same or more than you would with an off the shelf production system. If they're going to MIG weld it, make sure they use stainless wire. I do see that quite often where companies use stainless mandrel bends and don't even change out the spool/gas in their welders. When we do tacking with the MIG for prototyping we'll use 316 wire with Tri-Mix shielding gas. Works great. The Tri-Mix is CO2/Argon/Helium.
