Those are some good looking set-ups ya'll have
Couple of quick questions:
tasdrouille - what is your intake connected to? Looks like its attached to something close to your manifold cover maybe???? And that is made out of aluminum dryer vent elbows, correct?
cfg83 - does your intake sit directly on the manifold? Is the end a piece of metal dryer vent also? What exactly is that size reducer? it looks like some type of plumbing thingy????
