Changing your pipes isn't going to help you with gas mileage make sure your plugs and wires are maintained as well as keep the tire pressure where it needs to be

It depends. If all you want is loud then take a sawzall to your cat and muffler and weld in a section of pipe in their place. This will make your truck pretty much as loud as its going to get. However this will also make your truck illegal so if your in an area that checks these things its not a good idea. Also some people don't like the straight piped exhaust note.
Or if you want just replace your muffler with a less restrictive muffler like a straight through glasspack or reflective muffler. If your looking at an aftermarket exhaust look for one that is mandrel bent and about the same size as stock maybe 1/4 in bigger. Anything bigger is a waste of money on a stock truck.
Now like it has been said changing your exhaust doesn't automatically mean better mileage. I have a dual glasspack exhaust on my 97 tahoe and I still only get 14mpg(course I have a lift and bigger tires). However if a muffler is crushed or a cat plugged it will help big time. Sometimes however when you open your exhaust up a bunch flow becomes so much better that it actually hurts your mileage by allowing your air/fuel to pass right through the cylinder before it has a chance to close. All you need to do then is advance your cam timing.
Now on mileage, take you truck in for a tune up. New plugs, plug wires, and a clean high flow airfilter (like a K&N or other brand) will go a long way towards helping you out.
However the biggest determing factor in mileage is how you drive. you might need to slow down and not have so much fun with the throttle.
And if that was a little too technical for you, lets recap:
Mandrel bent exhaust, straight through muffler, or just take a sawzall to your muffler, a tune up, clean air filter, and slow your butt down.

The new vortec engine gets better mileage. Lould does not always make more gas mileage. Syenthic lubricants better quality tires not wider tires. Camper shell that fits tight to the cab. aerodynamic tricks like removing the outside rear view mirrors and replacing them with small cameras. No running boards or things hanging out in the wind. A good metal skid plate that directs air around the front suspension. I get 13 in town and 26 on the highway 6.0 liter LS-2 6 speed 400+ hp Pontiac GTO. Trucks are much bigger in the wind.

loudest pipes would be one inch glass packs, with out going to strait pipes that is. how ever that isnt going to help your mileage any. but you can run a slightly lager exhaust over stock and get more power plus a mile or two on a gallon. flow master is good, mbrp is also pretty good

1. custom exhaust system 2.5" aluminized-steel, with flowmaster (II chamber) mufflers & 3" tips.
2. K&N air intake (2nd Gen)
3. TB (Throtle body) spacer
4. NGK wires and spark plugs
5. Replace fuel filter and then add fuel injector cleaner in full tank, brand STP or other.
6. Check tire pressure in all 4 tires.
7. Use cruise control more often on highway.

Are you somehow equating noise with mpg? Sorry, but that does not make sense.

If you want it loud put straight pipes on it.
