4" unless you plan on putting down some serious power to the ground

Not at all, it will just be louder and cost more for the exhaust. The biggest down pipe you can run is a 4" and changing into a 5", so I see no need if you don't have a lot of HP to get a 5" unless you want it louder and for looks...

nope, just personal preference changes the tone to make it deeper, but normally a 4" is perfectly fine

If you want a 5" over a 4", It would have to be a or 3.5" or 4" DP to a 5". I do not think you can easily stuff a 5" DP.
