I have read all of the threads on Torque Loops, and would like to hear from those who have installed, and have put a few miles on the bike, and see if they think it was worth it. How does the bike sound with stock pipes vs aftermarket pipes. And which aftermarket pipes sound best with Torque Loops? I assume there might have been a few bikes with Torque Loops and a variety of pipes at the rally. wish I could attended.
