Wot does a four branch manifold for your car do??
Answers:
its just the front of the exhaust system isnt it.
Improves the removal of exhaust gases and , theoretically, gives you a more efficient engine.
All four cylinder engined cars have a four branch manifold, this is attached to the side of the engine block usually by 8 studs with nuts and in turn attached to the exhaust. Sometimes the gasket blows and you'll hear a proper racket much worse than a blown exhaust and your car will not run properly.
some 4 branch will give you more power
A manifold is the part of exhaust which joins to the actual engine. Depending on the amount of cylinders your car has denotes the amount of branches your manifold ie four branch manifold = 4 cylinders.
Absolutely nothing if you have a two port head.
If it is constructed properly it helps get exhaust gasses out faster. In a well designed exhaust the pulses from each cylinder will help scavange exhaust gasses during the crossover between the exhaust and inlet strokes. A badly designed exhaust can lead to local overheating and burnt valves and pistons.
Just like airways gum. It lets the engine breath more easily.
The quicker the flow of air the better.
It directs your exhaust smoke and fumes though your exhaust pipe
