Has anyone heatwrapped a V6 manifold ? (CF2)

HI

I am trying to heatwrap a CF2 manifold (catless) but it seems that the pipes of the right and centre cylinder (when viewed from inside the car) are so close together that the heatwrap wont clear them!

I can see a chap in Australia has managed to do it:
ausalfa.com • View topic - 147 GTA de-cat manifolds + full exhaust
But how ? Are my manifolds crap ?

Looks good!

I think my front manifold must have a manufacturing "defect" in that the pipes are too close together. Its down to 1mm...

My wrap might be a bit thicker than yours perhaps, its about 3mm thick on its own. ?

Yeah about the same as mine, when I got to the collector I just wrapped around all the pipes. Took me a while though

But then there will be a space in between the pipes that is not wrapped ?
I though that having uncovered areas was bad, no ?

I had mine ceramic and teflon coated on the outside. They even coated the heatshields and bolts for me... Its working well for me so far, no hotter temps either.

I was more than lucky, I have a good friend in the industry... he did it together with the other heavy metal parts that had to be ceramic coated.... putting my small piece of manifold into the mix, was just like an ant in the big scheme of things.

cost me some beer and good conversation
