Differences Between Headers and Manifolds

Exhaust manifolds are factory-installed components found on almost all vehicles, while headers are aftermarket upgrades. However, there are exceptions as some high-performance cars come from the factory with headers.

Manifolds are much cheaper compared to headers, as headers require careful development specific to the engine they are paired with, and they also use higher-performance materials.

Exhaust manifolds are designed by manufacturers to provide a balance of performance, fuel economy, and efficiency, while headers are primarily designed to offer optimal performance.

Headers often reduce exhaust backpressure, resulting in improved performance at high RPMs and the associated noise, while exhaust manifolds retain some backpressure to ensure driving performance across a wider range of RPMs and reduce noise.

Frequently asked questions
Will I need an ECU tune after installing this exhaust header?
A tune is not required but is highly recommended to maximize performance gains and ensure optimal air-fuel ratios. Tuning can improve horsepower, fuel efficiency, and drivability.
What is the difference between an aftermarket exhaust header and the stock exhaust manifold?
The stock exhaust manifold is designed to meet emissions regulations but restricts airflow. This aftermarket performance exhaust header features larger-diameter, equal-length tubing, improving exhaust scavenging and power output.
Do exhaust headers increase sound?
Yes! This stainless steel exhaust header enhances exhaust flow, creating a deeper, throatier, and more aggressive exhaust tone. It pairs well with an aftermarket cat-back exhaust for an even more noticeable sound improvement.
Will installing this exhaust header trigger a Check Engine Light (CEL)?
Since this exhaust header removes or relocates the catalytic converter, it may trigger a Check Engine Light (CEL). This can be resolved with an O2 sensor spacer or an ECU tune.
