Did it. Passed the inspection. May want to consult your local building code enforcement official. *Yes, as long as you do not increase or decrease the size of the ell when it turns up to catch the toilet. For exapmple a 4x3 closet ell goes from 3 inch to 4inch but due to its natural funnel design it is legal, but if you were to turn up a 3" ell and then use a 4x3 increaser it would be illegal, at least in my state it is, check your local building codes for further clarification.
