I'm just curious and I know that people are often secretive about this, but if you wouldn't mind posting a pic of a header jig, it'd help me out a lot.

I don't have a spare motor and wanted to try my hands at a header. I just wanted ideas. I know that tigwerks uses a big chunk of machines aluminum which would be great for heat control, but that sounds expensive. Would plate steel work?

Is there anything I should take into consideration?

Well the piece I have is $$$$ anything will work as long as it doesnt move and has all the important points on it. Mine is pretty overbuilt and is modular as well for different outlet styles for the header/headers being built.

You can make it out of square tube with 2 pieces of plate on either end to bolt flanges to or whatever tickles your fancy.

Do you measure out the flange bolts or just make the jig from a factory header and mic out the studs relative to that? That was my original plan but it doesn't seem super accurate.

I was thinking of making the flat plates out of steel and adding a copper sheet on top as a heat sink. Dumb move?

I would not use the factory header as those are a pain in the ass to install on a motor which means that if you use those as a reference your header will fit the same way. Measure from the studs on the heads and transfer those over to whichever material you choose to make a fixture out of. the part you are trying to make will only be as good as the fixture you build them in.

Kind of a crappy angle but here you go. I had a hard time finding jigs myself so I can sympathize.



If I were to re-do this I would use heavier gauge material for the framing to make sure it does not move at all and then it would be an ideal jig. I bought a 3/8" thick steel plate to weld the bottom frame to to help but haven't even used this yet so it's low on the priority list.

Also I based this off of an actual OEM part and not on the car because I didn't have access to the actual car but I'd agree that it would be better to do it based off the actual engine.

hope that helps.

This is awesome!!! Thanks
Am I looking at a jig for a low mount header or is that flange there to mark the oil pan?

Yea it's a jig for the 2010+ legacy GT header. I had originally planned to build a header for the car(I did about 5 "downpipes" for the car) but ended up not having time.
