So I drove around all weekend with my new cobb and I'm sorry to say that I can't get used to the sound. It's great when I'm doing spirited driving but normal driving it just gets annoying. Like on the freeway when you just give it a little gas to accelerate you can hear the sucking sound. I thought that I could just keep the music up and I wouldn't hear it. But I spend most of my time with my fiancee in the car so I keep the music low and now all I focus on is the sound. So I'm taking it off today and you guys will be seeing it up in the marketplace soon. If anyone wants a jumpstart on it you can PM me for it.
Wow! I guess this is a matter opinion, I love the way mine sounds and the noticable increase in power I got.
