White smoke

[99zq85spd]

There is a little bit of white smoke that comes out from my exhaust when my truck is cold. Its not when i start it its just when im at about 3 grand or so and kinda thump it a little. It will not smoke when i drive real easy and its cold. Is this something to worry about or to fix? Just wondering. Oh and by the way its a 99 5spd with a flowmaster 40 and no cat. Thanks!

probally just condensation in your pipes or a leaking valve seal.
Pull your plugs and check them. That'll tell you more than what comes out of the exhaust.

Plugs look good so its prob just condensation. Thanks alot

My dad had a 93 astro and it always put out real white exhaust when it was below 40 degrees, it had 125k miles on it, pretty sure it would be condensation.

white exhaust is a sign of burning coolant. maybe head gasket not sealing until engine reaches operating temp.(warped head, intake manifold) just somthing to look into.

No its not coolant at all. Just did a complete coolant flush and checked fluid regularly and it hasn't used a bit of coolant. Its prob just condensation from the exhaust because the cat is gone.

well i took my cat off and mine dosn't do that. condinsation dosn't burn white. it would steam if it did anything. but when i get condinsation coming out of my ehaust it just dribbles out. not smokes.
