That settles it, should be arriving on Tuesday! Thanks for the quick help!
Last thing, is that piping coming off the muffler something that has to be made?

If you're adding catless headers soon, personally I would do that first and see how it sounds with the second resonator. The stock exhaust manifolds suppress the M54's sound a lot.
Check out Gators' sound with catted tubular headers (from an M3), both resonators, and the Vibrant muffler:

I bet catless headers would increase the volume compared to this substantially. YMMV though; post up regardless what you decide. :)
Is the vibrant muffler alone louder than stock?
And I'm guessing the resonator delete could balance out the theoretical increase in backpressure from the 2.5" pipe?
The Vibrant Muffler alone is indeed louder and deeper than the stock tone. It is great, and the Vibrant Muffler with the second resonator is perfect IMHO. It is an affordable way to get an amazing sound, so happy I didn't go with a full catback, I have saved a lot of money lol
Headers are delayed now. Not sure if I am going to go that route, so second res delete will be coming soon.
Update:
I will be getting the second resonator taken out tomorrow. Luca will be tagging along on the adventure, so we will be able to get some nice before/after clips!
