It does too, and I like it too much, my gas card knows. I actually got asked if I had a turbo because of the sound. Sadly I could only laugh and say no, because there's no way I could ever back that. But yeah, it's true it isn't colder air, but it is less restrictive, ALOT less if you have a fram =(. But if you remove the silencer you start getting some engine air...at idle. Once you move, the hot air doesn't follow.
