    Hi Jj...

    What are you connecting here? What size is the vent that goes out the side of the building?
    Basically, we need lots more information to give a reasonable answer, OK?

    Hi JJ

    I would expose it in the right or left FRONT of the closet corner... most likely will never be seen tucked over like this.

    Also, note here that if you are venting an entire bathroom or even just a toilet and sink the minimum vent size in 95% of the United States is going to be a 2" pipe... ;)

    Questions? Let me know, OK?
