My personal opinion is that unless your going to a GTX28, the cyborg is the best current option for drivability and power mixed. The GTX has some happy owners as well, but its fairly costly comparatively.
As far as DHM making a stock turbo based tubular manifold, I wouldn't buy it or want it. I prefer cast manifolds ( and I'm not alone ). I think Adam at MAP said he was looking at a cast stock turbo manifold replacement with an external wastegate port. I'd take that opinion. Issue is... It doesn't exist, and you maybe really to trade the car in by the time it gets here ( it it does at all, who knows ). I would stop porting stockers (unless someone requested it ) if Adam cast a new high-performance manifold. Keep in mind, a DHM tube manifold would be around $700-$1200 and would likely have a bit more lag but more top end, for that, I'd recommend just going GtX.
I think the middle ground would be a TD04HL-19T. But... No one will build it because the profit margin on TD04's.
