Why Choose Exhaust Headers Over Stock Exhaust Manifolds?

Compared to stock exhaust manifolds, the Exhaust Header is made from lighter steel and features nearly identical pipe lengths connecting each cylinder, ensuring even exhaust pulses. This equal-length design effectively prevents exhaust gases from different cylinders from colliding, reducing backpressure and enhancing both intake and exhaust efficiency. As a result, the Exhaust Header is the ideal choice for optimizing engine efficiency and performance.
