IMO, I would not bother. I still run the OE twinscroll headers, even though I am now on a single scroll turbo (different up-pipe). I think the OE twinscroll headers are awesome. They are not a barrier for my 500+bhp and I know they have been used for 600+bhp set-ups. 
More importantly...... they stay in one piece.
