93-94 Headers.

hey im gonna order a 93-95 the only difference i noticed is that the 02 sensor is in the y pipe on the 93-95, and on my 96 the o2 is in the actual manifold. will it give it a bad reading or should it be fine, i will have to take the 02 from the manifold into the y pipe which is like a 10 in difference at the most but will i get a bad reading.

Don't know what brand of headers your looking at...but...my 93 had the O2 sensors in the manifolds and so are my headers.

What year is your car? I have a 93 and they are pacesetter headers as well. The only difference that I am aware of is where the egr tubes come up off of the headers. On a 93 they need to be on #8 and #1 primary tube 94-95 are in a different location. But I think O2's are in the same spot...but since I have a 93 I'm not sure.....maybe someone else can give some input.

I've herd from a friend that pace setters SUCK, he had slp's sold me those then got pace setters, got rid of those quick and went with mac's.

He said the fitment sucks and plug access was horrible.

If you're doing an AIR/EGR blockoff, they'll work. 93's had the AIR tubes over the #1 and #8 pirmaries, and 94-95 had AIR over #1 and #2 and an EGR Riser over #8.
