F-350 gas (5.4) where to buy dual exhaust

You may check the basic rags like Summit Racing or Jegs. I'm not sure about the F350, and if there's anything different about it that would affect the exhaust setup, but I know they have kits for F-150's and F-250's. Can't verify if they are true-dual exhausts or just dual-exit (single split into two), but you really won't gain a whole lot in going to duals over just a large single - it's mostly just a looks/sound thing, more than a performance issue.

Depending on whether it has dual cats or just a single cat, you could have an exhaust shop fab up whatever you want for about the same cost (or less) as a cat-back, too, and have them weld on whatever kinda muffler you want.

Heard good reviews on Gibson over on some other forums, as far as sound. Dunno anything about their fit or longevity, though, honestly...
