Headers (also known as exhaust manifolds) are the part that takes the spent exhaust gases from each individual cylinder of the engine, bring them together, and expel them from the vehicle (usually passing through one or more catalytic converters and one or more mufflers on the way). V-layout engines (V6, V8, etc) have two headers, whereas inline engines have just one. Usually, the term "headers" is only used for performance-enhancing aftermarket replacements for the factory exhaust manifolds. If a car needs new headers, that generally means that the existing manifolds have been damaged in some way. One common cause of this is rust.
Not sure what you mean by "new" headers. You probably mean the C++ standard library headers, however these headers have been in existence since before 1998 when the language first became standardised. Prior to that, C++ used the C standard library headers, all of which have a .h extension. The C++ standard library headers have no file extension.
Mikes needs an apostrophe. So the sentence would be: "Mike's car needs a new muffler and new brakes."
NO!
It means that the battery is junk and needs to be repalced. Time to buy a new one.
A car could sputter in the rain if the car needs new seals. There could also be a spark plug or wire that needs to be replaced.
hopefully you will be installing a new starter...
you buy the headers take yours off and put the new 1's on
needs new battery or fuse, needs new starter, reprogram or replace keys, reset NATS codes, needs new fuel pump, needs fuel in tank, needs new wiring, needs new ignition switch, needs new engine
You can't.
needs a new battery
The sentence illustrates a vague pronoun-antecedent reference. Who needs a new car Wayne or Kevin? The sentence needs rewording. Examples: Wayne told Kevin, "I need a new car." Wayne told Kevin, "You need a new car." Kevin was advised by Wayne to get a new car. Wayne needed a new car he told Kevin.
The old exhaust manifold will need to be removed. The new headers will either have to be made to fit the engine well, or the inner fenders will have to be modified to fit. Then the headers will need to be either mated to the old exhaust or a new exhaust system will need to be installed. In a v8 engine installation most people prefer a dual exhaust to maximize the headers capability.
