Default thundercones

Anyone know anything about thunder cones on a 08 roadking, heard that they really mess up the EFi pulses

I have no idea why they would. If you run open pipes such as drag pipes they prevent the reversion wave in the exhaust pipe from interfering as the exhaust pulse exits the cylinder. I had a carburated 94 FXDL the tune was near perfect but when I add the torque cones to the drag pipes there was noticible improvement in performance. The principle would also apply to EFI bikes.

I have heard nothing but good about the thundercones, in fact i am thinking of switching out my V&H classics with them. Carroll out.
