I have tried all three, open cone piperx, standard box with three pipe mod and panel filter and my current setup with a piper Viper.
Open cone was ok, but bogged down and soon seemed to get heat soak if stuck in traffic etc.
I have seen no loss of power with the viper over airbox, just get the bark around 3k with induction noise.
I don't think they do a Viper for the Z22SE but they are easy enough to modify and fit, or you could Venoms which come with reducers etc.
