Mazduh exhaust

Truck: 1999 Mazduh b2500 sx 2wd (blah...)
Problem: Exhaust rusty and noisy from cat back
Question: I DO NOT want to go to Midas or any such place like that. Does anyone have any recommendations (other than selling it and getting a 4wd!) for a performance system (not dual, i hate dual) of some kind? Maybe I could just go to the local muffler shop (like Smiths in Covington) and see if they can bend me something up? I say "performance" because this little truck needs all the help it can get! Especially because I'd like to throw some slightly larger wheels and tires on it this fall/winter. Any help would be awesome. Thanks!
