I just bought an 03 diesel ford crewcab dually. Its got a whopping 460 miles on it an Im itching for some mods. I want to know which exhaust system to run ( size 4", 5") and who make a decent system. Any cold air kits for this thing yet? Im open to ideas.![Big Grin :D :D](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f600.png)
