no.. lets say you have a port 5 inches wide and 7.3 inches long.. if you made it two ports both 5 inches wide the length would go to 20.5 inches.. more port area means the port will be longer.. now lets say you wanted the same port area but with two ports.. cut the width of the port down to 2 inches and then they would be 7.3 inches long so basically.. if you wanted to make two ports you would have to cut the width of that single port by 2 (in some cases more depending on the box) when you divide the port length in half
... i think lol someone correct me if im wrong though
