When doing a center port do you split the port length at the bend? Say I need 30 inches of port length, if my bend is at 20 inches is each side 10 inches or 5?
You keep the length the same but you cut the port area in half. So if your port is 5" x 10" x 30" long, it will be 30" long from the start of the port to the end of each fork. But the port will go from being 5" x 10" to 2.5" x 10" once it splits
