I am trying to find a CBE that I like, and the Hi Power sounds really good to me. At least the video's on youtube. I couldn't find any sounds clips from the inside of the car though. I was wondering for those that have this exhaust, is it loud or is it a nice deep rumble? Is there any droning? I was looking at the SR*S but from what I have read it is loud and has some droning (which I don't want).
