Headers that pass smog
I have a 1988 f150 302.
I want to get shorty headers that bolt up like factory. My problem is I can’t find any that have EGR hookup and A.I.R. hookup. I need the headers to accommodate those because I have to get smog.
Is there any that do this? I don’t want to do this work changing my ticking manifold for a stock manifold to go back on.

Will that fit my stock Y pipe? And the EGR and AIR? The problem I have is I need it to literally bolt on in every aspect that a stock manifold would, because I don’t have $600+ for a cat back plus a custom Y pipe.
I would just go with any header that bolts on but I gotta deal with these stupid smog laws.
I know it won’t pass with no EGR when it was broken last year it failed smog

Say I go with something that doesn’t pass smog, will this work?
if it does work how would the o2 sensor work?

You are best to go back to stock manifolds.
I suggested the Mustang shorties as they may have the thermactor, egr, and o2 sensor bung. But it would almost certainly require exhaust work to connect them.
Any header will require that as they always end up connecting to the exhaust system in a different position than the iron manifolds.

The EGR tube on 5L engines goes to the lower intake manifold, not the passenger side exhaust manifold.

There are no thermactor, EGR and oxygen sensor connections on the manifold. The air injection connects to the back of the heads. EGR is in the lower intake manifold and the O2 sensor is in the Y pipe. I have read that Mustang shorties will not attach the truck Y pipe so that isn’t a direct bolt on part which is why a truck shorty should be used.
Absolutely false. I have used two different brands of shorty header and they both bolted right up to the factory Y pipe.

Years ago I bought some short tube headers from Summit for my F150 with the 5.0.
You really need to watch the current size of your Y-pipe vs the connection on the header. I thought they were going to bolt right up but they never sealed correctly on the pipe flange. I went through a lot of work to end up with going na k to stock manifolds. And on top of that there was no real noticeable difference below 3500 rpm.

Are you in California? If so you know about the CARB exemption needed on aftermarket parts.
That's why I ended up saying go back to stock manifolds. They bolt up and no struggle with the smog test. Seems like the lowest cost most effective way to be back on the road quickly.

I am in CA. I heard about the CARB exemption. But I did see this has the CARB and EO #, so I should be good with smog? And since the EGR didn’t route how I thought it’ll just bolt in?
If these ones don’t work I’ll just go to stock. But it does run I’m not in a rush. I just want that tick gone.
