One thing people have failed to mention in this thread is that adding a catch can is not that straightforward. It won't fit with a normal bracket unless you swap the intake (you can use a Charger or SRT intake for budget reasons, or go aftermarket for an intake), because there is a silencer on the stock intake that takes up the space where the catch can would go.
Or you could get a fender bracket to allow you to mount it farther away. Those are more expensive, plus you need longer hose which will also be more expensive. Also some won't fit well with the stock engine cover, so you get into ripping that off, in which case your engine kinda looks like crap if you don't throw on some coil covers.
It is a great thing to add, but you need to plan it out a little bit as far as what you want in the long run.
