Mazda Miata Exhaust

I Know That I Need A New Catalytic Converter, But Will It Hurt My Car To Drive It For A Few Days (about 60 Miles/day) Until It Gets In?

My Car Has Developed A White Smoke Coming From The Tailpipe When I Turn And A Slight Knocking Sound When The Smoke Appears

My Wifes Miata Throws Out A Puff Of White Or Grey Smoke At Initial Take Off From A Stop. This Occurs After Warm Up But Does Not Occur All...
