when the valve is closed, the exhaust gas goes through the Y pipe into the passenger side.
If you were to do this, when the valve is closed, it would choke the drivers side of the engine, as the H pipe in the middle prob isnt enough airflow.

of course, if you do the golf tee mod.......the choking issue is not there.
How would it choke anything, I'm a bit confused. Doesn't the valve open once the car is warm or under WOT anyways? This is essentially another way to make a PE out of a stock exhaust no? Remove the resonated pipe and close her back up!

At least I hope.
