Cast HKS Exhaust Manifold

[Freebaggin]

Does anyone run or has seen or knows where to buy an off-the-shelf HKS exhaust manifold on their RB25? I can't remember where but I've seen an HKS cast manifold that from the outside looks like stock but I assume the guts of it is better designed for high HP and flow.

I have an internal gate Garrett turbo that is bolted onto the stock manifold and I want to see if I can get a better flowing off-the-shelf manifold rather than having to get someone to do a tubular one.

Thanks in advance.
