One of the benefits of getting a performance exhaust system is horsepower. Experts say approximately 10 percent increase in both horsepower and torque when those engine chains are broken. The reason being is because of the air flow referred as ‘breathing’. A faster expulsion burnt combustion gases due to an increase in the diameter of the output channel. Backpressure is dismissed and the engine is free to work on its combustion cycle. Other benefits include sound, and fuel mileage.
