I would assume that I am going to make a tad less boost since I have no cats. I'm just trying to see if upgrading the HX is a must or just a preference. I would be tracking the car a lot. Maybe here or there. And it's not my daily driver. Just driving around, not getting into boost, should be just like it is now.
