It's not a STUNNA mod, it's a free mod for people to do that don't have $. I took it out so that I could hear the turbo, and it did make the car louder than when I first bought it. What do you drive? And I still have the INTAKE SILENCER, and at one point I will probably hack it and put it back in, but for now, it's out, and I enjoy the sound. You have no idea what you're talking about.
