Default Fluttering sound from 2.5

Hey y'all, quick question.. maybe the answer is really simple.

When my car is coasting in gear and no throttle is applied, I can hear some fluttering sound coming from the engine bay. This doesn't happen when I give it some gas or hold the rev at certain rpm's, but only when the car coasts in gear without throttle. Why?

Intake mod is the Minnam short ram, and also, the cone filter right on the throttle body (currently).
