I have the LV's on my bike, actually this is my second set.
With the LV it comes with a new mid pipe, 1st generation were one piece new ones are two pieces.
This is the thread to the 1st generation install.

The advantage of the Q4 is it uses the stock mid pipe which is nice in the sense it keeps the gaskets etc and seals up better.
I dont have any pictures of the new pipes but they are smaller in overall diameter less oval. The original pipes I had hit the caliper on the rear.
