Here is my dads 2004 f250 superduty!! it has the 6.0 diesel, with dual exhaust. everythi8ng else is pretty much stock... hope to get a 4inch dp on it soon as well as more lights and an intake kit....  it has 33" cooper st's on the stock rims.

HERE IS A QUICK VIDEO OF THE DUAL EXHAUST, 3 INCH FROM DP TO REAR AXLE, THEN SPLITS TO DUALS, AND INTO 5" TIPS....
