Yep mine is a 160, and I had "subtle" pops and burbles added, not so it sounds like a machine gun going off, I have a scorpion back box though and this helps I would guess.
Third gear really is amazing 25 to 70mph, 2nd is insane with the Rev limit raised as per the new map.
overall a better, more fun drive if you want it, or nice steady power delivery for "normal" driving (changing gear at 4000 revs)
I love the Jekyll and Hyde side of the car, it's like it has a split personality....????
