If you leave the stock exhaust on there its not going to help a whole lot, but if you do what 351M said, 2.5" true duals w/ see-through or no mufflers, it will wake your truck up, assuming its not turbo.
I wouldnt even bother witha muffler. soon im going w/ a 3" turbo downpipe to a 5" pipe...it will exit in front of my rear pass. tire

DONT put the exhuast infront of the rear tire!! Big mistake. The whitewall lettering on my tire is blak within a week after washing it and if I dont polish my rims the smoke eats away the chrome finish and leaves rust spots all over. I want to get my stacks on soon before the new rim looses all its finish.

Non turbo with a straight pipe is pretty loud. At idle, it just has a slight rumble. But under load and decelerating from higher engine speeds, its pretty obnoxious. If you're easy on the throttle, it doesn't arouse too much attention from the law. I haven't felt a power increase, but the mileage dropped a little. Mainly because I'm shifting about 2800 instead of 23-2500 rpm just to hear it make more noise (and to rattle the windows on the imports a little bit 
)
