Pipes for intercooler?

[SmbFD3S]

Ok, have just got some HKS hard pipes for the SMIC and wondering where i can get the crossover pipe from in hard pipe form ?
 
This is the one i mean circled:-
 

 
And yeah i know i need to replace the flex connections lol... Will do for the time being
 
Anyone know what size they are and best place to get them from, as i forgot to measure them and want to order them today if possible ?

You could try looking for the efini Y pipe and crossover - best place is America but sometimes people sell them on here too.  Im just waiting for mine to be delivered
