I'm not a fan of really loud pipes. I get enough of those with all the Harley guys crusing around the neighborhood. I have TORs and they have a very sweet sound. But to each his own.
Pack em with Silent Sport and they sound great. They are pretty loud out of the box, but they seem to be holding together well and look good. I have 4k on mine and after repacking them have been a happy camper.
got mine from specialty spares. Found them a bit loud - and too "blatty" for my liking, even after repacking. So went for TPUSA dominator tourings instead
