I agree! I have the cat bypass without TORs... Sounds meaner than the jap cruisers, but not obnoxious... Extra noise as made by most Hardleys and R3s with Jardines, TORs, etc. gets really old on long rides... At least for me.... My dealer stated that most of the extra performance comes from the cat bypass and associated tune code.... The TORs only add an incremental amount of performance.... He recommends them for people that want the sound and not necessarily that much more performance...
