| The JWT inlets are very nice - cnc machined with a o ring groove in them. Z1 now has the same groove for the o ring and the bracket is heavy duty steel. I'd say that Z1 sorted out the problem with the leaks they might have had before. I also prefere the outlet on the Z1 kit. It allows for a full 2 inch outlet thats the same size on both sides unlike the OEM style where the driver side is smaller than the passenger side. I'd say the Z1 setup is easier to service as a result. Harry
