The horsepower (HP) gain from a Flowmaster exhaust system can vary depending on the specific vehicle, engine configuration, and the type of Flowmaster exhaust installed. Generally, users can expect an increase of about 5 to 10 HP, though some setups might yield slightly higher gains. It's important to note that these figures can vary, and actual performance improvements depend on how well the exhaust system is integrated with other modifications and the overall condition of the vehicle.
