On Cat-Back Exh... I saw somewhere that if stock has a crossover pipe, your aftermarket needs one too. I don't think there is a distinction between X and H configuration. Noise restrictions too but it you have a stock cat you will probably never get "hassled by the man" for it.
CAI... I think any mods are OK in front of the MAF sensor.
No alternate cats where listed last time I checked.
