Get headers from an 88 car, or buy aftermarket headers. Those are from an SN car, and you have no use for that bung on the header pipe.. So there is no way for you to "legally/properly" hook it up.

And no the actual name is not EGR pipe, it is just part of the EGR system. You would have to get a diagram of the EGR system for an 88 and see what you are missing and go from there.

 

Ok, I have some pics. And by the way, it is a Mark VII, not mark VIII. But the Mark VII uses Fox body headers so those that you have are SN95. I have a 90 Mark VII with only 88K miles on it
Let me figure out how to attach them.

The first picture is the whole system
The second pic is the part that attatches to the rear of the air pimp. The right side clamps around the outlet on the air pump.

 

This part bolts to the rear of the cylinder heads and is attatched to the top hose of the Y in the main hose that hooks to the pump.

 

This tube goes from the bottom hose in the Y to the pipe between the rear cat converters.

 

This is a Fox header. Aftermarket Nickel plated MAC headers. About 15 yrs old and has never blown a gasket!! Not bad for $125 new. Notice no EGR supply tube like on the 94-95 Mustangs.

The EGR valve is fed internally thru the intake and it is shown in the second picture.

 

Here is a pic of running no smog pump with a 77" belt instead of wasting $70 or so an a pulley that wears out. There is about 3/8" clearance on the belt, never has rubbed using a Dayco or Gatorback belt.

Second is just a picture of the old beast after 161,000 hard miles. Still runs pretty strong!!

 

if you went 76.5" you would have even more room between the belt on each side

 

No need, the tensioner is right in the good range and it never rubs. But. Yes I could have.

 

I run a 44.5" belt on my car... heh I hope it never breaks, It take two people to get it on because you have to unbolt the waterpump pulley to get it in place.

 

lolol
