It actually changes between Sequential Pairing 180* 1 & 2 . 3 & 4 , and Non-Sequential 360* 1 & 4 . 2 & 3
Sequential and Non-Sequential is a term I see used by SMSP when refering to their headers.
180 VS 360

Problem is I see people saying that the valve increases backpressure and that is what helps the low end... they think it's just a
restrictor but actually it's switching between 180 and 360 so backpressure should be the same.
found a nicer full picture, I guess depending how you have to install it will determine which pairing you will get to use.
