ok now i am confused if i use one 4in port i need 5.85 inches but if i use 2 ports its says 13.62 inches is that a piece or divide that between the two ports?

NO thats the length of each port. if you increase the port area you need to increase the length to compensate.

the length it gives you for any amount of ports is for each individual port.
