Um - double check tomorrow, but I THINK it's about ~ 90 °C. I should know this, must be getting old.

Vettech:
About Ceramic lagging and coatings, I've not used them but have heard they can cause heat stress in the metal causing cracks in welds and at bent points.

Petrol engine running at full load has exhaust temp in the range of 560 deg C to 700 odd depending On a variety of factors .

That's more for exhaust wraps, rather than coatings, ceramic coated headers/extractors normally last longer. The ceramic coating holds up much better than paint, and if it's internal as well then it stops the metal from ever getting as hot. Wraps on the other hand trap both heat and moisture in with the steel. They can also be wound on too tight, restricting expansion of the pipe when it gets hot. Wraps may reduce the life of headers/extractors quite a bit.

RHD vet you need to fabricate an L shaped bracket which bolts to the two spare bolt holes on manifold below carby on L/hand side. Then run cable out around the front & back onto carby
