Why do people say they got some headers for their Suby or Honda or what ever last time I looked our car and other 4 cylinders only had one exhaust manifold...Am I missing something?? Maybe we need to have a common car terminology thread.

 

i have suggested it before - its just a matter of one of us guys compiling everything and making a sticky- the thing i suggested was something like a glossary...

Hahahaha! This reminds me of the "buttplug" incident.

This is something I've inferred because I've never read or heard anything stated as truth.

My understanding is that an exhaust manifold is obviously stock, as well as made of a iron (heavy), and not very efficient with regards to flow, whereas headers are aftermarket, generally of some space-aged, lightweight alloy like 4130 or 4140 chromoly, is nicely designed to facilitate flow and deter turbulence.

Of course, I was assuming.
