I strongly suspect this is the case, just based on my driving impressions. I think we are trading low-rpm torque for high-rpm torque with these headers. The car feels less torquey (less "jerk" if you will) at low rpms (idle to 3k -ish). It's actually kinda nice, since the car now drives smoother at grandma speeds in heavy traffic. Again, we'll see once we get some headers on the dyno.

Hopefully they can include the low RPM range in the plot, a lot of the time they start things at 3K.
