How Vehicle Headers Work

Carrying Away Engine Exhaust Gases


Headers are typically installed on cars by a vehicle owner seeking to accrual the horsepower of his machine's engines. Headers are incomplex exhaust tubes or exhaust pipes that acquiesce for the faster exiting of burned engine exhaust gases. Traditional exhaust manifolds are somewhat restrictive to exiting engine exhaust gases and produce a bit of engine backpressure, which reduces engine horsepower and restricts Gauze milage. Headers, on the contrary, typically compass larger exhaust tubing and definite tubing designs that enable exhaust gases to Way out a vehivle's engine faster and in worthier quantities. Headers, besides allowing exhaust gases to exit a car's engine faster and in greater quantities, serve to bridge the gap between the engine and its main exhaust system components. Normally, exhaust gases, after flowing through and exiting a set of headers, travel to a car's catalytic converter, where these exhaust gases are reignited and burned. After traveling through the catalytic converter, exhaust gases travel through a car's muffler and then out of the tail pipe.



Header bolts attach directly terminated the header flanges and actualize an hermetic seal, down which exiting engine exhaust gases travel directly into engine headers.


Funneling Exhaust to Remaining Exhaust Components


As exiting engine exhaust gases flow through a set of headers, these exhaust gases are transported to the remaining components of a car's exhaust system. This leads to a lowering in engine backpressure and an accretion in both engine horsepower and Gauze milage.

Bolt Headers to Engine Exhaust Ports

Automotive headers, which accept the lay of factory-installed exhaust manifolds, simply bolt directly to an engine's exhaust ports, which are the openings in a van's engine complete which exhaust gases flow gone. Headers admit Apartment lodgings areas (header flanges) on their exhaust tubing ends that affiliate directly against the side of a motorcar's engine exhaust ports.
