Possibly found an OBX 4-1 Header...Questions...

-Will it fit my SPI, or would I have to move the flanges?
-Is it worth getting?
-To get the most, would I need to do an exhaust system?
-This would help breath easier correct? MPG?

It is N/A and from a zetec, never installed.

Bump for night viewers.

Headers do help MPG, but the exhaust ports on a ZETEC don't match the SPI meaning the head flange won't work not to mention if the firing order matches.
The Escort GT header is really the only option without getting a head flange from JGS Tools and building it yourself.

They do have the same firing order. I checked that.

How much do they not match by?

A fairly good amount lol
