Decent video.
In person it sounds good but is too loud for my taste. It actually got annoying after a few miles. If you're trying to attract attention this is the exhaust for you.
I really need to hear some exhausts in person. I don't like a single one online. I want something with a nice deep sound that isn't obnoxiously loud or raspy or 'poppy'. The 11's just don't sound as good as the 4.6's.
