Most Cobras you would have to repair the cutout in the body. There may be a couple of Cobra where the sidepipe leave the engine compartment under the body. I don't know of any but maybe.
If you could find a good fiberglass body man he should be able to repair and paint the area.
I would think the color and age of paint would be a factor.
Ask around. Look for shops that do Corvette body work.
The exhaust system would be easy.
