There is a small amount of white smoke that comes out of the exhaust when rev'ing the engine to 4-5k rpm when the car is in neutral. Is it possible that an off road pipe with no cats could cause this?

What was the outside air temperature? How humid was it? How hot was the engine and exhaust?

about 65 degrees outside. Not that humid at all. Engine and exhaust were warm from already driving the car.

I'm suspecting you're just seeing a bit of water vapor in the exhaust condensing as it hits the cooler air outside the tailpipe.

If you're worried, keep tabs on the coolant level.

All of the gauges for oil, temp, etc look normal. I guess I can keep an eye on the coolants. Any reason to think it might be something else?
