Sounds like most people put a 3" GM right before the 3000 pipe

Yeah, but how? 2 1/2 - 3" reducers on each side? I'm planning my install & want to do a blow thru, but I think that using reducers on each side would screw with the airflow, right?

2.5 to 3.25 actually.

reducers wouldnt cause enough turbulence to worry about, and also there is a honeycomb inside the maf that is supposed to reduce turbulence/straighten airflow.

yes you can mount right before the throttle body or on the throttle body for that matter and use a 3.25 to 3 or 3.25 to 2.75 reducer.

however, on my setup i tried to keep as far as possible from the heat of the motor and exh manifold and also from electrical noise of plugs/wires/coils. being a elect tech i always avoid heat and noise as much as possible.

here is how i did mine. will be changed soon when ffi goes on.

hope this helps
