I have a Millek system on mine. Iirc they are the same as VWR just different branding.
With regards to drone, at 120/140 you would know you driving a car with a catback. It's designed perfectly, when you WOT then you hear her scream. Under normal driving it like a normal car maybe abit more bassy than stock.
Performance wize I don't know where to begin. It makes a huge difference. The car is so much free on the open road. Better response, revs up instantly. I did pick up more wheelspin so it definitely has increased some power compare to stock downpipe
