No, the turbo will spool up quickest when there is the greatest
possible pressure differential between the turbine inlet and outlet.
In simple terms, that means as little back pressure as possible
after the turbo...
Now a great idea (I think) would be to put the cat BEFORE the turbo.
It would improve emissions AND add even more heat to spin the
turbine with. That should end the EPA whining about turbos and
cold-start emissions that are a big reason for the lack of turbo
cars on the market.

I think it was a good thing...Chris?
