The factory mufflers are pretty much straight through if you look through them. Our 99 has straight 5" on it and it's pretty obnoxious but I'm too cheap to spring for a muffler. Also has 285/75/16 tires and they're too big in my opinion. Rob a fair amount of power and not worth a nickel in our red clay.
I'd be more concerned about the mismatched lug nuts, the two that don't match are not the correct profile mating surface for your wheels and may very well loosen up over time. Be a good idea to replace any like that on the truck with factory style for safety purposes.
Nice truck.
