What headers are these?

looking to see if anyone knows the brand that these headers might be. My issue is that on the drivers side header there was a stamp with EO # and manufacture welded to it. However sometime over the past years the welds broke and I no longer have the smog information I need.

My goal is to see If I can find out who manufactured these so I can see if they can send me a new information plate that I could weld back on myself.

Maybe an older style pacesetter. Mine have the plate at the same spot.

Re: What headers are these?

Thank you for the reply. They look similar, I noticed pacesetter has single pipe for each cylinder. Where as the ones I have have multiple welds per cylinder. But like you said maybe an older pacesetter set so I will call them in the morning and see what they can tell me.

Re: What headers are these?

That appears they may be a "step" header, with the first couple inches of each primary a smaller diameter than the rest of the primary. JBA made a single-cat step header, but they didn't look like that. I've never seen a set like that before.

The look funny but they are shaped exactly the same as my pacesetters. 70_1335

Re: What headers are these?

thanks for the input guys

I ended up sending a picture to pacesetter and they confirmed they are not theirs. Same design but they stated they only use single bent pipe per cylinder and do not do have any that are stepped like mine. they suggested headman or JBA but both looked different...

I wanted to get this smogged so I just ordered a set of pacesetters 70-1335 and am now done with it until I get new smog results.
