for a fixed volume of air flowing, as you increase the flow cross section, you need to decrease flow velocity to achieve the same volume flow rate.
the trumpet attempts to drive the cross sectional area to infinity and thus the flow velocity to zero. not a lot of friction when you have zero flow velocity.

Reading the first post, they simply removed the stack while the car was on the dyno and ran it again. Couldn't the hotter air entering the turbo inlet vs the cooler fresher air entering the mouth of the stack account for the 2-3% drop in power.
