thanks for posting the video, I also just installed mine about 2 months ago and put on few hundred miles, sound is def better on start up, but driving under load about 2300rpm/2500rpm there is a huge drone compare to stock.
Don't know if you have that issue, but mine does, in the mean time my n55 mid came in few weeks ago and I'm about to put it on to see any improvement.
Trying to have a feel for it before and after the n55 midpipe. Will post the my result on here if you don't mine since I have the same exhaust.
