I hear what you are saying if you can afford a $800 to $1000 pipe, why not spend an extra $100- $200 to get it dyno tuned for best performance and have a graph?  Its a PIA for me , time ,extra cash do not always flow together at the same time to spend on toys.
  I am sure there other dyno graphs are out there on the New V-2 that will read a heck of alot more H.P. than mine has, maybe some members will step up and post them soon.
