First picture is entire dyno with Air/fuel at the bottom.

Next pict has an inset of the crossover region enlarged.

The blue curves are the TRD exhaust and red are stock exhaust.

Keep in mind, the Torque curve is the flat one, which starts going up a little at 6000 rpm then drops off after 7000 rpm. The HP graph starts low and eventually plateaus from 7000 to 8000 rpm.

The car is a 2000 Toyota Celica GTS, "stock." It has a drop in K&N air filter, Mobil 1 10-30 oil, Redline synthetic tranny oil and the exhaust changes (for the blue curves). Stock, the engine is rated at 180 hp, so the 160 at the wheels translates to a 12.5% drivetrain loss.
