Macht Schnell pulley. Do you have a stock xpipe with the secondary cats still? The Fabspeed xpipe did do a lot to free up that exhuast flow. That was the first part of the exhaust I changed, then the AE rear section, then the TTPs.

Some of the difference could also come from whatever Karl down at Active Autowerke added to the file. Frank sent it to him for some additional tweaks on which he had been working.
