Why upgrade the exhaust manifold?

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

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