Easy installation (although the holes on the plate that mounts under the fuel injection pump do not line up, it is easily repairable.) The new throaty sound was quite an unexpected surprise. Of course there is a noticeable HP boost as well, esp. on startup and around 5000 rpm. Hard to tell if MPG is better since I like hearing it so much right now.
