The point of the resonators to quiet it down and prevent some drone, without noticeably affecting power. The real question is do you still have the factory cats? If you do, you'll probably be fine to remove them. I'm assuming you are thinking of removing them because it's not as loud as you'd like?

That being said, everyone's tolerance level for loud exhaust is going to be a bit different. Personally I think people who complain about drone in these cars has never owned a car that really drones. My Mustangs droned, especially on any car with an H-pipe, X-pipes helped quite a bit. When I think of a drone, it's more of resonance frequency inside the cabin thats to the point that almost hurts. My 370Z I ordered Fast Intention exhaust, no resonators (one of the biggest reasons I chose FI originally was this option), and have Berk HFC. The car loud when you accelerate, but when you cruise it's fine in my opinion. I can have a conversation, listen to the radio, etc.

The car will be louder when you put aftermarket exhaust on it, the closer you make it to a straight pipe, the louder it will be. You either want a loud car, or something that's quiet for road trips. You can't have your cake and eat it too.
