Hi:
White smoke is usually an indication that coolant is getting into the combustion chamber. This is usually the result of a bad head gasket or other problem with the head. You may want to have a second opinion on the topic.

Also, why would anyone drill holes in the exhaust system? First, it will not pass inspection, and second it increases the chances of CO2 poisioning.
