It is

I'd recommend A-spec for a quality manifold. Only downside is for the FC the manifold is only avalable as a package with turbo wastegate downpipe lines/fittings/etc. Although it can be a pricey package altogether, its all super quality stuff that you'll need anyways for goign single. I purchased a 3574 kit in their august sale last year for about $2400.

EDIT: Noticed your last post. The cast stuff is also great, I've ran one for YEARS and loved it but wanted better spool up etc. If you're planning this route take note of the engine flange as I had a used one and needed to get it surfaced because of some tiny exhaust leaks there.
