Why upgrade the exhaust manifold?

Upgrading the exhaust manifold to high-performance headers offers several advantages:

  • Increased Performance: Aftermarket headers improve exhaust flow, reducing backpressure and enabling the engine to produce more horsepower and torque.
  • Enhanced Durability: Headers are often constructed from high-quality materials like stainless steel, offering better resistance to heat and corrosion than stock manifolds.
  • Improved Fuel Efficiency: By optimizing exhaust flow, headers can contribute to better fuel economy under certain driving conditions.
  • Aggressive Sound: Upgraded headers often produce a deeper and more aggressive exhaust note, enhancing the driving experience.
  • Customization: Headers can be tailored to specific performance goals, such as improving low-end torque or maximizing high-RPM power.
