if you dont see the difference with a volant intake, you wont feel or see a difference with any. volant is by far the loudest and gives a truck a descent kick.
i absolutely agree with sudden urge, do you have exhaust work? they kinda compliment each other. the in works with the out. if you dont have any exhaust work, before you try selling your intake, maybe consider even a simple magnaflow muffler upgrade. just my .02
