How restrictive is the Ford Racing X Pipe

How restrictive is the Ford Racing X Pipe?
It seems that the intersection is very narrow.. doesn't that restrict airflow?

The Pipes being 2.5" means that at the intersection around 3.5"

Is it enough for a 450hp 430lb-ft car to run its whole exhaust in a 3.5" tube??
