Why Good Headers & Exhaust Systems Matter
At 4,000 rpm, a 3.3L (202ci) Holden Red Motor draws in approximately 6,600 litres of intake air per minute and expels around 19,800 litres of exhaust gas per minute at approximately 600°C.
A well-designed header and exhaust system helps this volume of exhaust gas leave the engine efficiently, reducing unnecessary restriction and improving exhaust scavenging, torque, throttle response and engine performance.
Warranty & Compliance
Pacemaker headers are backed by Pacemaker's 2-year manufacturer warranty, subject to the manufacturer's warranty conditions.
