Why Good Headers & Exhaust Systems Matter
The supercharged 5.0L Coyote V8 can move an enormous volume of exhaust gas under high load. Unlike a naturally aspirated engine, the supercharger forces additional air into the cylinders, increasing the amount of exhaust gas that must leave the engine.
The PH4170's large 48mm (1⅞") primary pipes and 76mm (3") outlets provide substantially greater flow capacity than a smaller exhaust manifold or header design. This becomes increasingly important as engine speed, boost and power output increase.
A correctly matched high-flow exhaust system helps reduce exhaust restriction after the headers and allows the complete system to take advantage of the PH4170's increased flow capacity.
Warranty & Compliance
- Backed by Pacemaker's 2-year manufacturer warranty under standard warranty conditions.
- Correct installation and adequate clearance around the headers are required.
- Warranty applies to the supplied components and does not cover labour or consequential costs.
- Modified, competition and high-performance vehicles may be subject to additional manufacturer warranty conditions.
- Verify emissions, noise and registration compliance applicable in your state or territory.
