The exhaust systems on the JK Wranglers allow very little flex. This causes the forces that the exhaust sees from the engine torqueing to twist the exhaust system instead of allowing it to flex. Over time the weakest part of the exhaust system (the manifolds) fails, causing cracks to develop. It is highly recommend that a flex-pipe is installed into the down-pipe of exhaust system with the installation of replacement manifolds. This will allow the forces that the exhaust sees to be absorbed by the flex-pipe instead of passed onto the manifolds.
