I have Cobb's 3" turboback and I love it. When I first got it I thought it was too loud but the sound has grown on me to the point where I now think it sounds great. It is quiet when I short shift and don't use full throttle, so I can avoid annoying the neighbours.
As far a power goes, a huge difference over stock. I made more power everywhere, and reach full boost by 3k rpm. I should also point out that my ecu is reflashed to cobb stage 2 as well, which is probably a large part of the change. I _strongly_ recommend that you look into some kind of engine management to go with a new exhaust.
