Sound is available
If you'll do a search, somewhere on this site, I think it is on Dave Dragons site, there is an audio of the Remus. I've got on and would be happy to have you give me a call and I'll turn it on for you. (813 267 8181) Installed mine several years ago, by following the instructions from members of this site and could not be more pleased. I really don't think it is "that" loud and like the difference. Probably not any faster, just sounds different.
