Default Light smoke from exhaust

Hey all, recently i noticed after i rev the car slightly a very small amount of blueish smokes comes out (very light not alot) the car has no cats so just plain test pipes, doesn't smell like coolant nor oil burning just reg catless fumes. Ill leave a video so you guys can see it. Any help is very appreciated.

did it just start emitting the light blue smoke recently or has that been going on for a long time? have you made any changes to anything recently? Blue is concerning because that's the color of your coolant, if you're using Asian coolant.

That looks like water vapor. It's normal.

Next oil change, measure how much you drain. If you have no oil leaks, that will tell you whether your engine is consuming oil or not.

Just wanted to give you a heads up that it's pretty normal to see a slight blueish tint in your exhaust if you have a catless setup. But don't worry, just keep an eye on it and make sure to monitor your oil levels.
