Header install.

Going to be getting militarymase's header in a day or so.

Wondering about the egr and second o2 sensor.

Its an 89 lxi and pacesettter header.


Do I remove the egr? Assuming no, will remooving one o2 sensor throw an engine code?

[POS carb]

leave the egr connected.
the Pacesetter header is smog legal and should have o2 sensor and egr holes

K ty.

Another question is, what size the the header andd downpipe, 2 inch?

And would increasing the pipe after the secondaries to 2.25 make a difference?

I have a test pipe and 2.25 mandrel catback currently..

Thx

I know the pacesetter catback is 2.25", I am assuming the header is the same

i think mine was 2inch on my pacsetter same with the DC if i remember right. its just all in the bends and weld qualities.
