Explain these two tanabe exhaust CR-Z dyno graphs
 

One is for the Concept G, and the other is the Touring Medallion. The touring model makes more power, yet I've heard the concept g makes more power on our cars, and it would stand to reason considering it's design. Maybe with an intake on there, the picture would change in favor of the concept G? Obviously the design of both is different than the GE8 models, but thought it was interesting information for consideration and discussion. The IMA shouldn't effect these figures as it relates our car, at least regarding where the power curve departs from the stock one.
