6.0 stock exhaust options

So I'm considering either the catalytic delete pipe or the stock muffler delete pipe from Pure Diesel Power for my excursion. Looking for a little extra noise, but nothing deafening. Not as interested in HP (no studs yet) but mainly mileage gains. I figure I'd go 4" stainless if it weren't for the extra price that I could be spending on gauges, maintenance items, or parts for my other cars.

Which one of these pipes will give me the best increase in mpg?

Is a no muffler/no cat straight piped diesel too loud for daily driving given the giant cabin of the Excursion?

You are not going to see a mileage increase with just an exhaust. Not enough to really matter, at least. You could always just strait pipe the stock exhaust. It wont be loud until you get on it.
