I have A Motordyne TDX2 Exhaust system with Art Test pipes and a Injen CAI.
When I give it gas in 1st and 2nd gear (normal acceleration shifting at 3k roughly) Some white smoke comes out of the exhaust.

What could be causing this or is it normal from a catless system?
My mods may be causing me to be running lean?
I am burning oil, but from my understanding the smoke is usually blueish.
I check my coolant and I don't think that level has changed at all.

This white smoke is concerning... do you guys have any input/thoughts?

 

This is typically the rule of thumb:

White - coolant
Gray or Blackish - oil
Blue - unburned fuel

Does it always do it? Or just sometimes after you first start driving it?

 

Slightly blue is oil usually.
I was using oil from the valve covers (now repaired with R&D kit), and have decats BUT I had the car remapped when they were fitted.

 

Is it colder out by where you are, and does it go away after the car warms up? One of the products of of combustion is water, and in cooler weather and a free flowing exhaust it evaporates much more quickly. Also, outside moisture can collect in the exhaust and evaporate as the exhaust heats up.

Otherwise white = coolant, keep an eye on coolant levels, oil (look for milky residue, especially on inside of oil cap), and if the smoke smells "sweet."
