I found saw this on ATP's site the other day. This is something that I actually thought of doing with an e-cut and some kind of controller, but this seems much more efficient.

If it wasn't so expensive, I'd get it right now. Even though an e-cut and y-pipe costs about the same...

This idea came to me when I was in the N/A frame of mind, D16's need backpressure at low RPM's to create low end and then more flow at the high end.
I seem to remember thinking the same in a turbo setup. Is this true at all? Obviously for the NA setup this wouldn't work since it opens off boost, hence the e-cut and RPM based controller idea.
