aftermarket exhaust

What kind of exhaust do you think sounds best for either a ford or chevy half ton. I want it to sound stronger than the stock exhaust but I don't want it to shake the ground or anything. Any suggestions on the cheapest way to do that.

The cheapest way to change the sound without making it sound awful is to replace the stock muffler with an aftermarket performance muffler of roughly the same size and dimensions. You have to measure what you currently have. They sell a lot of inexpensive decent quality performance mufflers at places like Summit Racing and Jeg's.
