Mine came on the car when I brought it.
It's not too loud, sounds ok on the power, nice noise when you let off. Adding test pipes soon though so I'll see what it's like then.
The tips have lost the burnt titanium colour but other than that the system looks ok, I'll know more about how it's holding up when I install the test pipes.
Long term I'm going for the ARK Grip, seen / heard a few and it's definitely what I'm after.
