Which size exhaust to go with?

Nah, what you want is those high buck electrical exhaust cut outs that Summit sells. Then you could now and then, at the right times have NO mufflers on that motor :finga:

But don't go crying here if somebody filps out on you.

Yea, would be a lot easier and quicker then uncapping the headers and driving around, like I did once back in high school.
