What's this do?

Just had an exhaust manifold arrive(thanks Jesse) and I was hoping someone knew what this was for?

Hi Dan,

That will send exhaust gat to inlet manifold.
I think they are used in USA and Canada for emission control. So not important in UK.

Can always rely on Leo for an answer.
Thanks Atchi!

for california spec models.
my cultus intake has the other half of the set up lol

Kind of a waste of time now I think about it. It can't draw much gas to warrant a significant drop in emissions and it must make that final exhaust port slightly restricted if a vacuum is drawing gas back in to the engine.

the cultus intake i got had a load of old oil blocking the tube anyway so it was even smaller that it could flow through. im sure i read somewhere it was a stupidly small amount that it reduced emissions by.

im sure the intake draws the exhaust gas through so if urs is a standard normal intake it wudnt make any difference wot so ever to you.
