What nipples to reach the front & rear rotors
 

Have got a JDM S5 TII and am considering doing the "water cleaning" of the rotors with it. I know you have to use a vacuum line that will feed both front & rear rotors, but is there one on the JDM manifolds that is easily accessible that feeds intake runners to both rotors, or would I have to use 2 separate nipples and T them together?

Cheers for any thoughts on this one :)
