New to this forum. Just thought I'd try a search for a 03-07 5.9liter factory exhaust system. I'm probably going against the grain but the 3500 I'm working out of has been straight piped at one time then someone did a substandard job of adding a muffler back to the system. I'm really wanting to find a factory takeoff system to go back on with. I know there has to be some out there floating around. If anyone has one they are wanting to part with let me know. Thanks
