What do headers do to a car?

I’m just curious, what do headers do in a car? Are they better or worse than exhaust manifolds?

Great question! Headers are a built-in part of the exhaust system in many cars. What headers actually do to a car is route gases away from the engine and to the exhaust system. T
This is essentially the same purpose exhaust manifolds serve—but headers are slightly more advantageous because they cause less backpressure. This, in turn, results in better overall air circulation for your engine.
