If all you are doing is using the Bronco for daily driving with some off-road, all you need is to open the exhaust. A set of shorty headers will not make it a drag racing king, but will help to clear the exhaust gas.
But using the factory exhaust manifolds and opening the exhaust pipes to a larger size. The factory system uses both 2 1/4 inch and 2 1/2 inch inside diameter pipes on the same system. Increasing the inside diameter of all the system to 2 1/2 inch or 3 inch (pipes and mufflers) will help get rid of that exhaust gases faster.
