Can exhaust manifolds be replaced by headers?

Yes, headers can effectively replace traditional exhaust manifolds in an engine's exhaust system, offering several performance advantages. Unlike the single-piece design of exhaust manifolds, headers have separate pipes for each cylinder. This design improves exhaust flow and reduces backpressure, resulting in increased horsepower and torque.

Advantages of Headers:

Improved Exhaust Flow: Each cylinder has its own separate pipe in exhaust headers, allowing for smoother and more efficient exhaust flow. This reduces backpressure on the engine, enhancing overall performance.
Increased Horsepower and Torque: With reduced backpressure, the engine can "breathe" better, leading to increased horsepower and torque output, especially at higher RPMs.
Enhanced Sound: Exhaust headers can alter the exhaust note, typically producing a deeper and more aggressive sound compared to stock exhaust manifolds.
Replacing Exhaust Manifolds:
Upon installation, headers replace traditional exhaust manifolds. Instead of a single-piece manifold, headers have separate pipes for each cylinder, which then merge into a collector that directs the exhaust gases into the rest of the exhaust system.

Frequently asked questions
Do exhaust headers increase HP?
Headers can increase horsepower, improve the flow rate of exhaust or improve your car's sound. No matter what you're looking for to enhance your engine system, you can find an exhaust header to suit your needs.
Do headers make your exhaust sound better?
With exhaust headers, your exhaust notes will be smoother, more defined and far more aggressive.
Are stock headers better than aftermarket?
An aftermarket stock header deals with the exhaust gasses in a much more efficient way, which improves the overall performance of your engine. Performance headers are more concerned with increasing performance rather than reducing the noise from the engine.
Will headers increase gas mileage?
To really maximize fuel economy, performance headers are manufactured to a shape and size that improves engine “breathing.
