Any cold side pipe you want. Hot side is DHM specific.
With the ATP kits, the turbo sit in relation to the OE set up to be able to use the stock oil drain tube and downpipe.
The turbo with a DHM manifold does not sit in the same location and requires a different downpipe, oil drain tube and hot side charge pipe, so you will not be able to use one that fits like OE with modifying it.
