Why Choose Exhaust Headers Over Stock Exhaust Manifolds?

unequal length stock exhaust manifold-irregular pulses, limited flow
suncent exhaust manifold header-even pulses, maximized flow

Exhaust headers, made from lighter steel, feature a nearly equal-length tube design for each cylinder, ensuring uniform exhaust pulses. This design prevents exhaust gases from different cylinders from colliding, a common issue in manifolds that creates back pressure. By reducing such interference, exhaust headers enhance both intake and exhaust efficiency. In contrast, exhaust manifolds, made of thick iron, are shorter and prone to significant back pressure, which hinders engine performance. This makes exhaust headers the superior choice for optimizing engine efficiency and performance.

FAQ

Does an equal-length exhaust header really make a difference?

  • Yes, the key to improving exhaust flow in an exhaust header lies in the equal-length design. This design reduces exhaust pulse collisions at high engine speeds, thereby enhancing engine breathing efficiency.

Is SUNCENT's equal-length exhaust header 100% equal in length?

  • We must be honest; due to space constraints within the vehicle, it's challenging to fit complex piping, so it cannot be 100% equal in length, as compatibility comes first.
