I have a 04 F250 SC 6.5' bed with the 5.4 I wouls like to put the stock OEM exhaust system back in it from the engine back. Was wondering if I can use a system from other years and engines without to many mods? I had the Walker replacement in the at pone time and it rotted out and no longer want the aftermarket spound. "I guess I am getting old' LOL
