I put a volant on and hated how loud the system made my truck sound under the hood. I am sending this unit back and wanted to know if anyone has the afe stage 2 magnum air intake system and does it sound louder than stock system. I see where they have the turbo resonator hooked to it so I am wondering if that quiets it down. I got better gas mileage with the air box system on so I believe in them but just was annoyed with how loud it made it sound under the hood. Thanks for your input.
