Hey TOgenshi.
I have seen a similar concept on a YD25 C RD Navara. What the guy basically done is, put some sort of a Y pipe on the clean air intake. One goes to the normal intake as per usual, and the other one was piped into the EGR system. This kept the original flow of things but instead of the dirty gases, clean air was flowing through the EGR pipes, keeping the system happy, while keeping the engine cleaner.
