I never came back an update with some later videos I made including some on track. I know earlier during the thread some of my videos were posted. These are all from the setup I have which is VRSF catless downpipes and Active Autowerke Signature Exhaust (Single 3.5" from front all the way back to muffler). Only first video was with OEM downpipes.
