What was the amount of smoke before and after of the installation of just the catch cans?

Can you provide the link of the cans. And what size outter an inner diameter of the hose?

I'm not sure if yours came with the updated breather hose or not. Mines had the older Y shape hose which is shared with all 4 points. So i would think 1 can with T 'd off hoses would look cleaner. Lets all agree that the x5 has way to many wires and hose under the hood. Lol
