The only way to pass the OBDII portion of inspection without cats is to use an O2 simulator. I'm working on one as I write this, utilizing a microcontroller and adjustable PWM signal. If it was as simple as getting a tune, many others would have done it already.
A legal tune that doesn't throw a check engine light or return "not ready" does not exist.
Note - this is for the U.S. only. I don't claim to know the laws of other countries.

@Salman: Is the above statement correct? if yes, then i told you multiple times that i have no cats at all and the answer is to just remove the O2 check. what about EGT in this case? awaiting your feedback. THanks.
PS: we have no such law in my country, my car is at 115 db also
