The Stock exhaust had been replaced with a true dual setup and the only problem I have had is the Flowmaster Turbo mufflers had rusted completely out, other than that there have been no problems what so ever.
This Truck has never failed to get me from point A to Point B and it is one very strong workhorse in the mud and muck.
The 5.9 litre V-8 Magnum powerplant has more than enough power to get me out of any situation I happen to get in.
I have A 2500 quad cab 4 X 4 and it's off road ability sucks. Their anti spin differential should be junked. Every Dodge on the trail gets stuck in the same spots. If you really intend to off road, put OX lockers or ARB in the rear. I have been embarrasssed too many time and have learned my lesson.
