If you're looking for a way to add a little more power to your F150, one option is to install a cat-back exhaust system. This type of system replaces the factory muffler and exhaust pipes with aftermarket components that are designed to improve airflow and performance. While there's no guarantee that you'll see a horsepower increase from installing a cat-back system, many F150 owners report gains in both power and fuel economy after making the switch. If you're thinking about upgrading your truck's exhaust, a cat-back system is definitely worth considering.
