long tube header question

[jdevs1]

I went to change pass side header gasket on my 89 GT with what I was told were MAC long tube headers and found middle tube just slides into collector. It doesn't appear to leak, but just wondering if it was suppose to be welded up. Anybody ever see this type of header before? Mac doesn't show them on their website.

It's probably suppose to be welded up. I would call Mac and ask them. Are these new longtubes and you are putting them on. Or are they on the car already.

it does not need to be welded. hooker does the same thing

Really I never knew that. The Mac longtubes I had were welded all around.

No welding. Just slide it in. Most likely they are Hooker Supercomps.

My Flowtechs arent welded together.

Thanks for the replys the headers were on when I bought car.

most but not all full lengths are slip fit to make it easier to drop in.
