I have a 2000 FXDWG and want to to further customize it. I've done a Stage I kit and am not realy satisfied (I should have research more, but that is what the dealership recommended). I've just ordered the service manual and am mechanically capable (I've worked on car engines, etc) of doing my own work. I'd like to increase the performance and loudness as well as get a "thumping" instead of "purring" out of the engine. Am I limited by the SE II slip ons? Will the Dynojet give me the "thump" that I want? Any other suggestions are welcome.
