Yes on a standard exhaust I will try and get some vids up failing that I can email short clips from my Iphone
It's pretty good for £35 bit of popping on dsg change

Up to say 3k rpm you get a nice deep sound no real pop on gear change just a noticeable noise, 3-5k rpm you a pop from the exhaust under swift acceleration, 5k - redline normal dsg fart but louder,
You can drive this around and not know that it's been done.
I do get a small pop on downshifts very small tho..
