muffler delete

How loud would you say it is?
Also how much does it drone?

very loud.. especially on cold start (almost embarrassing sometimes). When the car is warmed up it sounds wonderful. Especially from the outside. Drones enough to make you feel like your head is going to explode between 2500-300 rpm (about where the car is in 6th gear at 70-80 mph). For the money you cant beat it but I would say add some hundred dollar mufflers to try to help with the drone. Since you are in a warmer climate its not so bad as you can have the windows open so the drone doesnt resonate in the cabin

I have never used this before but I have to right now

There have been 2 major muffler delete threads in the past with plenty of videos and info about it.

Alex pretty much summed it up, but here are the videos of my car. But if you a lot more info on it just read a little it will go a long way.
