If a Scotts style filter out filtered an oem style paper filter, then you would not see every motorcycle manufacteror on the planet using paper oil filters. The sotts filter does outflow a paper element but it does not out filter it. this stuff has been debated for years. Some very expensive race engines do use a scotts style filter but those things run one day and are rebuilt the next. I have never seen a filter of comparable size both outflow and out filter another. You have to make a choice.
