Why Good Headers & Exhaust Systems Matter

• A Chrysler 318 V8 engine draws in approximately 11,100 litres of air per minute and expels around 33,300 litres of exhaust gas per minute at 5,000 rpm [@600°C]. Efficient header design plays a major role in allowing this volume of exhaust gas to exit the engine smoothly.
