The exhaust manifolds should be the same. the best way to find out is to call or visit your local dealership and have them check the part numbers. I doubt that there was a 220hp 3.9L engine, however any horsepower difference in the engines would probably be through camshaft design and/or software programming. The best way to increase power is to install a low restriction air filter and exhaust system. Headers are also an option.
