the brake duct system i put together is 2 parts. one is from the undertray to the inner fender liner and the second is from the inner fender liner to the backing plates. so far i have only done the first half of the system and will run it like this to see if it gives enough extra cooling. if i am still having issues i will add the second portion in the spring or summer time. i bought 3 inch flanges from summit made from aluminum that i already used to attach the tubing to the inner fender liner and these same flanges will be utilized to mount the tubing to the backing plates. the system is 3 inches and i think routing will be nearly impossible without a significant amount of rubbing so hoping i dont have to tear it apart and do the second half at all. there is an entire write up of this titled apex gt4 brake duct install.
