"As I said it’s one of Q’s early pipes he was selling before they started stamping them...Anyway, these early pipes scream on the top end with a more violent hit.  It’s my understanding that the stamped versions make more low/mid power but this one has them on top.  Would be a good hill-shooter/drag pipe imo, as it runs hard."

Send it to the 'Dyno Curve Shootout.' I bet it would sell fast with a graph attached.
