An engine has one header(exhaust manifold) for each cylinder head it has.
Engine specific. T he headers need to bolt onto the exhaust ports on the engine so regardless of the car the engine must be the same
usually
What engine and car they were designed to fit.
adding headers will allow engine to breath better and boost up horsepower but not by much, headers also make you vehicle louder with pipes.
You will have to remove the engine.
i have a 2007 mustang gt 500 with bbk headers how many horses is it
There are too many variables that determine what hp increase headers will give. Engine size, carbed,f.i.,stock,hi perforforman ce,car weight,the list goes on and on....
No.
Headers help the engine breathe better thus better performance but the rest of the exhaust system needs to be included.
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.
Headers are the pipes that connect to the exhaust heads. Commonly referred to as the manifolds headers are more often made of pipe that have been engineered to create equal back pressure to the engine at each exhaust port on the head, thereby allowing the engine to run more efficiently and evenly.
They help the engine "breath" better.
