I can get any size, the problem is getting it to work with the port size. IMO it would be too restrictive going from the std port size down to a 1/2" tube. A reducer could be made to make the transition smoother but at what cost?

Here is an update:

ALL of my headers are now made with matched ports. I've actually been making them all like this for a while just haven't posted any pictures.

The headers are welded on the port side and ground smooth as well as welded on the backside (outside).

This one pictured is not welded yet.

I would say it was missing a hole, but then I would have to admit I was missing the money to pay for the missing hole so it isn't really missing a hole after all :(

Still looks great :thumb

Maas, could you please price me out a header that's just like your standard version, but with 1" primaries instead?

I was contemplating doing a stock bolt-on header, but thought better of it as a long tube should provide better low end torque than the stock shorty version. I also do not have a catalytic converter on the car so I will only need the collector that's 1.5" in size and no flange on it, just slightly enlarged so I can slip it over my stock exhaust and use a stainless steel band clamp to seal things up.

Could you just reply in this thread please so everyone can have an idea of what this will cost? I know there are others out there that would be interested in this same thing probably.

The price would be the same as a standard header. $200 plus shipping.

The EGR and 02 bungs are optional as well at no extra cost.

My only concern is getting the 1" tube to fill the whole port on the flange. I may have to try some 1" this week to see if it is possible or not.

What about swelling the tubes a little at the end?

That what I have to do with the 1.25". They fit nearly perfect. The 1" might not be a problem, I just need to try it before I start to offer them for sale.

I'm ready to pay as soon as you can confirm it's doable.
