I do remember your post and we replied back and forth a bit about it...and
even have a copy of the original post in my inbox.

I was unaware from our correspondence that torque decreased down low.
Perhaps it wasn't as big of an issue to you since I assume on track your car
rarely sees lower rpm.  Oh well...the joys of email communication.
Since torque rules for autoxing, I'll be chucking the straight pipe and
hopefully getting a Borla in the near future...hopefully the Borla will
increase torque down low (?).
Made for an interesting experiment none the less :-)
