Is that what this is?

Do I really need it in a track car?

Thanks.

Most of the catch cans I've looked at have an "in" and an "out".

Does the "out" need to feed back into the air box?  It seems redundant if there's a breather on top of the catch can.

That pipe is the line from the carbon canister from the fuel tank breather system.
