"Replacing the resonator with a 3" outer diameter piece of pipewill net you NO performance gains. All that will happen is a slightly different intake growl. The resonator is essentially a muffler for your intake. The length of the pipe is irrelevant. It simply needs to be long enough to allow the filter and the other intake pipe to clamp to it, and short enough for the filter to fit in the area without hitting the radiator hose. So somewhere between 1.5" and 9"."
From first hand experience...the "Butt Dyno" can tell a difference in the mounting locations.(I prefer the AFM)
The only issues found thus far are those that live in Texas and Florida, sometimes have issues with a hot engine, and hot weather. The intake temps with the afm mounting method alters the voltage of the afm(I assume thats what is happening) and produces a bad idle.
I used a 3" aluminium pipe for a while before changing it over directly onto the AFM. It becomes awkward in the stock location with a pipe instead when removing the shroud for an e-fan, that's why I changed to putting it on the AFM if I remember correctly.
