Missouri Code drain run on the outside of drywall?

[Jjayg7]

Hi! Remodeling the kitchen and moving the sink from an interior wall next to the stack, to an exterior wall about 6 feet from the stack. Can I run the drain behind the cabinets along the wall and connect to the current stack connection so as not to drill through the studs on the load bearing wall?

I don't know of any code that won't allow pipe to be run outside of a wall.

only certain walls have fire rating issues where penetrating the rated wall . other wise a pipe isnt required to be in a wall . Ive done it many times
