[QUOTE="BrianChia, post: 3615535, member: 576132"] Generally speaking the length of the ports will be proportional to total port area. If you have 1 4" port at 20" long, then you would need 40" or port for 2 4" ports. If you cut the port area of the first port by half and add another port elsewhere then the length remains the same. For example, (2) 10"x2" ports at 20" would be roughly equivalent to (1) 10"x4" port at 20". However going from one 10"x2" port at 10" to two 10"x2" ports would mean you would mean both ports are now at 20" since the area doubled. [/QUOTE]
