I purchased the V&H Monster Rounds for my '12 Ultra. Almost sounded stock above 1500 rpm. Asked V&H about alternate baffles or removing fiberglass from new mufflers. Tech stated all sound waves are killed before exiting the catalytic converter and the only way to get more was to remove the cat. I purchased the Power Duals and got exactly the sound I wanted. Also remapped the PC-V and eleminated a high RPM surge in the motor. Not sure but I believe the cat was choking the system. HP & Torque & MPG went up, Right Thigh temp went down.
