I don't know what kind of exhaust system we are talking about here, but!...
If the car has a catylitic converter, then the higher the RPM's, the more it
will stir up the Platinum beads which in turn will reduce the HC in the
exhaust,
otherwise, I would lower the RPM to normal. Just don't go over 1300 RPM
becuase
then it's not considered low ilde emissions and will fail.

I didn't mention this becuase of the way some people may feel about
synthetic oils.
I think they are fantastic. And oil and oil filter change will do
wonders for the states car enema test.
Synthetic oils are 100% lube and the crude oil has properties that are
pollutents
and is not 100% lube. Synthetic oils are cleaning and can also increase the
chance of passing on a normal running old engine that is border line.
