#304195 here to clear up the mani question:

the d15/d16 manifolds WILL bolt right up, BUT depending on which motor you're running will greatly determine which mani is right for you.

i am running a Z6 mani on my D15B. works fine, BUT the port sizes are different which effects how much air my motor gets.. which isn't ideal.
