sc14 piping

[ashzv6]

Hi,
As some of you may know i,ve been doing a d.i.y sc14 kit.
But now all i need is piping but i dont know where to start.
should i have the flanges remade with some 3 inch piping on it?
the inlet/outlet measure 2inch x 4inch so how would i get a pipe on there?
is there 2inch x 4 inch piping available anywhere?
Has anyone done they,re own piping for this kit?
Can someone please post up pics,
Thanks.

hey guys,
should i hack my old metal 3inch chrome intake and use it for the outlet?
is it worth it?

than just use some silicon adapters and some hose clamps?
by the way i would cut it along the red line and use the right angle peice to the throttle and blower outlet pipe already there.
