I am going in next week to get a set of TOR's not my first choice but the easiest as far as I can see but thats another story. what should I expect response wise and how loud is it going to be
I'm very happy with my TORs, Wildrooster. They are not all that much louder than stock, but they give a presence to the 2300cc motor. They won't offend the neighbours. I put Roadhouse slipons on my Vulcan 2000, and they were too loud for the Chosen One so I had to change back to stock. She has no problem riding with the TORs on the R3T.
I assume you are getting the Triumph retune with the TORs ? I can't tell you what the HP increase is with the Triumph tune (there certainly is an increase), but if you're not happy with it, for an outlay of a couple hundred $ Tuneboy will give you a big whack of the RIII Standard/Classic power back (just make sure you use the correct version of the Tuneboy program

) I'm sure Harry or Pig9R will be along shortly with more detail on HP/Torque gains.
