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.

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

The Benefit of a Equal-Length Exhaust Header:

Unlock Greater horsepower with Enhanced Torque

increase the car's horsepower and torque.

The exhaust header can boost horsepower by 8% to 12% and torque by 6% to 10%, making it a must-have choice for those pursuing optimal performance.

Optimize The Vehicle Weight Distribution

enhance engine performance and prolong its lifespan

The exhaust header, made of lightweight, thin high-quality stainless steel, reduces weight by 10-30 pounds , bringing the front-to-rear weight distribution closer to an ideal 50:50 , enhancing acceleration, handling, and braking performance.

Transform Your Vehicle’s Sound

improve the engine roar during driving

An exhaust header enhances the exhaust note, producing a deep, commanding tone at low RPMs and a thrilling, passionate roar at high RPMs.

Boost Fuel Economy With Optimized Exhaust Flow

FAQ

What is the difference between a long tube header and a short header?

  • Long tube header add more torque at low and medium speeds. Short header are the idea choice for a balance of performance and noise at high speeds.

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.
