Which of the 2 outlets is for the fronts and which for the rears?

 

Or is does it not matter which way round they go?

 

 

When they go from the m/c where do they go, basically i want to know if i can join the front pipes together with a t piece and the same with the rears to take it down to 2 ports instead of 4 (1600i has 4 ports) surely if its only got 2 ports they either front and rear or left side and right side, either way i should be able to join the pipes to make it work, its just finding the correct ones to join

 

I need to find out summat or the car aint gonna be going anywhere
