Opinions on exhaust

Flowmasters are up there on the loud scale, I personally don't like them though because IMO they have too much of a tinny, rattley sound. The Dynomax Ultra Flos are louder (but still quiet at cruise), as are the Hooker Aerochambers. I believe glasspacks are the loudest but have a much less "polished" sound to them and are a bit restrictive unless you get high-quality ones.
