I have a 2008 FLHTC, stock motor, K&N Air Filter, V & H Fuelpak, Rush Slip-ons. Happy with the sound from the Rush Slip-ons but was thinking about saving some weight and maybe a bit more power by going to a Sampson Powerflow III 2 into 1. Has anyone heard these on a Twin cam? I like the sound of Sampson Pipes I've heard in the past. I was also thinking about the V&H 2 into 1. Any feed back to the sound and performance of these 2 into 1 pipes. I like low, loud rumble.
