Yes the reason your 5th and 6th ports are not opening is because that pipe is not hooked up. Your ports open with exhaust backpressure. That little pipe runs from your catylitic converter to your exhaust manifold. The pipe is also used to heat up the cat to help lower emissions. You might have to take your exhaust manifold off to weld that little pipe back in. Good luck. P.S. Clean the actuators on your 5th and 6th ports to make sure they are gonna open once the split air pipe is working again. Aaron Cake has a good write up on his site on how to do it.
