Default White Smoke?

I was driving home today and my sister (who was driving behind me) said that when i really punched it, she saw white smoke come out the exhaust. Not a lot..and i tried it a few more times and she said it got less and less...the car had only been running about 5 min. any ideas what it is? i have a hks exhaust and a CAI with a K&N Cone Filter.
Thanks

it could be a few things, but without any more info i would lean toward condensation in the exhaust.

How many miles do you have on the car, you might need to change the valve seals since it was only running a few mins. But I could be wrong, just giving you something to think about.

definitely worth thinking about, but you would probably see some smoke on start up. valve seals tend to leak after the engine has been turned off, unless they are way bad. the car will smoke on start up b/c oil has pooled on top of the piston

Sounds like a head gasket, the color is indicative of coolant entering the combustion chamber. What's your coolant level look like? Good chance it's only happening under full throttle, so the issue may only now be presenting itself.
