I don't understand why this sport seems to bring out so much hate among-st its participants. Everyone just assumes the other guy is an idiot, and always in the wrong. Just once, many of you should try to put yourselves in the other guys shoes.
Back on topic.... there are options for aftermarket sound compliant, both in terms of the law, and general goodwill to non snowmobilers, silencers. As long as they are not significantly affecting the back pressure of the two stroke tuned exhaust, which most of them do not, it will play no significant role in the "break in" procedure of a snowmobile.
People have success turbocharging 0 mile brand new sleds. A different muffler designed for the stock bore, and stroke is not going to play any role in break in procedure.
