There is an advert for a second hand stainless header for sale near me and I'd like to go for it but the only question is will it fit my engine?

Header has come off of a D15B2, its 4-2-1

I have a D16Z6 in a 94 Civic Si

There is a hole for the lambda sensor at the collector just before the flange for the cat, so 1 sensor not 2. I think as I run OBD1 then this is fine.

Am I talking crap or will this work on my car?

Please let me know as I want to grab it before it goes, if it will fit.

Thanks

 

You might need to extend the wires to the sensor with some headers.

 

Okay thats no problem, I'm okay with wiring. But will the header bolt up correctly to my head? No leaks or clearance issues?

I assume all D series heads will accept the same header?

 

The assumption would be true, however if it's one of those cheap no-name headers it will most likely leak.

 

Any D series header is interchangeable. Like stiff said it sounds like its one of the cheap no name brand ones that will always run the risk of fitment issues.
