Yes, you are required to have a muffler.

my truck has no cats and a flowmaster 40 right now.and its about to have no muffler too.i've never been pulled over for it bein too loud,just don't get on it right by a cop and you're fine.and even with emission testing i can make it pass.i just went and have mine checked the other day and it passed everything but it failed because i don't have any catalytic converter on it.so that just proved that my fix does work.i wanted to try before i put the cats back on,i gutted em but didn't feel like goin through puttin em back on.just remember there's a legal way,and there's the more fun "legal" way,i choose the latter,always more interesting that way.
