Thanks for the reply. That was the official "Nissan" fix but then they started using splice kits.When I had my fix I just bought it from the dealer like 3 days before I went back to them and had them fix it. But from my understanding, the pipe goes the full length of the SUV and the car has to be separated from the frame/base and then a new pipe lay in it. So stupid design IMHO, sorry I can't give more insight.
Others have had luck with the same and it prevents having to lift the truck off the frame. That's the route I will go.
