ive seen some cars have 2 beather tanks in the set up, dave had it on Yum and fudgey also had that sort of set up but just wondering how it all plumbed in and the benifits

i got a imprea that has 2 heads but the breather tanks available only seem to have a catch tank with 2 ports and they seem to T- the 3 ports on the engine together and then vent to atmosphere but it leaves the manifold 1 way valve not connected

i know that cossies have 2 block breathers 1 head and 1 return to the sump/catch can and one at the bottom to atmosphere

i currently have a old cossie breather from my cossie i never bothered selling ( surprise there pmsl) so wondering can i fit that set up to a catch can set up perhaps

anyone give me a guide of the 2 can set up ect please
