Don't really know, but on the TQC that didn't seem to occur.  However, I
still effectively have two mufflers...the rear Dynomax unit and the ANsa
tip.  The overall effect, then, is that there is a longer straight pipe run
behind the catalyst...which I would think would help low/mid torque
response, if anything.
