So I just got this in and my garage is doing the install and there a bit useless so I have to stay on top of them. Does anyone know if I need to order any additional clamps or couplings to install this pipe with the rest of the stock piping? It came with a silicone coupling on the side that connects to the turbo but nothing else, does the other side that goes onto the stock piping just clamp together without a coupling? Can I just reuse the stock clamps ? Thanks a lot
