Has anyone done, or seen - dyno comparisons between he 4 and 4,5 inch Freedom Exhaust slip ons for the TC? While one might think the larger muffler is better on such a big engine, I would want to make sure I didnt lose any low end torque from the bigger pipe.
 
I have the 4.5in Freedom Performance exhaust and BugBike stainless cat delete headers on my TC. I have no idea on if I may have gained or lost any hp or torque. I feel zero difference in performance after these changes and I ride pretty hard. The sound my TC now makes is amazing!!! Note: when I purchased my pipes Freedom did not make a set for the TC. I had tomodify the lower saddle bag support to install the Freedom mounts as they are designed for the R18 and Classic not the B and TC, at the time. Also they were too short for the TC which led to me finding another solution to extend the exhaust tips past the bags.
