air suction pipe?

[nskforlife]

what is the pipe callled that runs from the exhaust manifold to the intake manifold? what is it's use, and what would happen if it was removed?

stupid question, i know, but maybe someday it'll all add up.

thats your egr tube and if it were to be removed you would have a big exhaust leak its for emissions

thx. all i needed to know lol

you can delete it, but you will probably flunk visual inspection on emmissions testing. Just cut the pipe 2 inches from the manifold fitting and roll the end like a toothpaste tube, lots of hammering, welding optional.


All it does is vent fresh air into the exhaust pipe in between cylinder firing. I believe the purpose of this is to make the catalytic more efficient (or to cheat on emmissions tests!) . It runs on a reed valve setup under a certain RPMs...

The egr also known as Exhaust gas recirculation system is supposed to dilute the fuel-air mixture to lower the NOx production under combustion.
