So, it's looks like I'll be purchasing a 2016 3.5L F150 here in the next few days. I've heard the debate about catch cans but would like to hear from the members here. So, what do you think? Are they absolutely necessary? If so, which is the best no-drill option? If not, why not? I'm inclined the think they're not required as much as a peace of mind kind of thing. The combination of PI/DI should keep things fairly clean. But, what are your thoughts?
