Newbie Exhaust Questions

I am going with a Flowmaster 40 Series Delta Flow muffler. I have a couple questions.

1. What is the stock exhaust piping size on a '08?

2. I would also like to have dual side exit, which would you recommend?
Center inlet/dual out or offset inlet dual out?

3. What size outlet do you recommend?

4. So many exhaust tip available, I chose flowmaster because it does not sound 'ricey'. Which type of tip and size would give me the deepest sound?

 

the pipeing is 2.25 inch inlet and outlet. running a Flowmaster is bad for performace, if your wanting something for sound then this is what you need. if your going for performacne, get a magnaflow
