Question, need some help

I installed some catless dowpipes about a week ago and now the car just started smoking white smoke out of the exhaust pretty badly. Im not sure if this is related to the downpipes since it didn't do it at first. Anyone know what this could be? I need some help asap! thanks

Don't worry, this is a common problem which should go away within a few weeks. If the problem remains for several months, you may have a blown turbo seal which could be leaking/burning oil.

mine does the same especially when sitting outside all night with damp weather. Hopefully is only water in the exhaust. It does not smoke one bit warm.
