[QUOTE=Triaged]1) Because it does nothing to hurt power output
2) Because the computer will throw a code if you remove it
Well, my 77 don't have a computer
3) Because it is against federal law (and in many places state law as well) to remove it.
Wrong! Depends on which state and how old your car is. Mine is 28 years and exempt.
4) Because it will help reduce NOx emissions making the air we all have to breath a bit better.
Well then, that's gonna wipe out 3/4 of the hot rods on this board that don't run the EGR...
