I would go with 2-1/4 or 2-1/2 inch tips at the rear. Most people are use to bigger tail pipes these days - whether muscle cars with upgraded 2-1/2 or 3 inch exhaust pipes or imports with big fart can mufflers. A 2 inch tip will probably look smallish and less original than a slightly larger one to most people on the street.
