None of them sound like imprezas, either. In the videos it seems like they sound more like an impreza, but in real life it is a bit different.

I think my car is the one you are talking about without the rasp. Personally, I like the sound of it now. Was a little worried when I first installed the header because it is quite loud but it has a very nice, deep rumble to it. I have the JDL header, stock over and front pipe and agency power catback. I'll try to get a vid up in the next week.
As an added bonus, the JDL header gave me a torque curve as flat as Miley Cyrus's ass. Overall power gain wasn't what I hoped for but I'm going to try replacing the over and front pipe and see what that does in terms of hp and sound.
