- Everybody hates the TGV's, but once they are ported, they are a nice gradual, smooth transition from a round port in the manifold to the heart-shaped port in the head. The engineer that designed them did a nice job really. It's a good port shape, but unfortunately interrupted by the TGV flapper and divider.
- A manifold that bolts to the TGV is simpler, quicker to develop, and less expensive, so people who already have ported TGV's (and there are lots of them) will be arguably better off.
- When I do a TGV-less manifold it will be for top feed injectors only, so people with 04-06 STI and 05-09 Legacy GT would be left out.

I may do a "street" version with smaller/longer runners. But under 400-450whp I don't think the intake manifold is holding people back much. But still, the stock WRX/STI intake manifold is a poor design at any power level if there is an FMIC.
