First of all, HI!! New Focus owner here and looong time Ford owner. I just bought a brand new 2017 Focus ST this past Saturday and so far, I love it! With that being said, me being the automotive nut that I am, I know every vehicle has room for improvements. I have been reading about the much debated catch cans for the turbo cars. I also realized the posts were a few years old and haven't seen anything new posted about them. Those of you who have them installed have you seen any benefits for the cans? Any follow ups on these systems? I want this ST to last (since I'm going to be keeping it for at least 72 months) but I also would like to improve on it's performance down the road once I have put some miles on it. Any suggestions, comments, concerns from current ST owners?
