We've never had any of the intakes that we've installed on our own trucks make a popping sound, and I haven't ever heard any personally to try to pinpoint it. The prevailing theory is that the popping only occurs when the intake isn't seated all the way in the lower half of the air box or if it's connections aren't totally tight, allowing some movement when throttle is let on or off. There's not an intake that's immune from that, so you really should just pick the one that you like or fits your budget.
