Pipes are Samson Rip Saw's. I like the turn down on the ends cause I believe it quites them down some and it has more of a "thump" which really likes to set off car alarms :-) Performance wise they are not the best, but they came with the bike when I bought it so I just left them on.

P.S. I heard that the girls like the vibration of the HD, didn't know about the loud pipes :-)
