What I'm looking for is a material that exhaust piping could be made out of, use close to the head or even for the exhaust runners for the header.
The material would need to expand internally without cracking whe heat increased.
Lets say that the internal diameter of the piping was two inches...
This is purely a theoretical topic right now...
Trying to find a metal or combination of metals of piping that allow for a certain amount of thermal expansion, while still maintaining their visible structure. Or really, more along the lines of thermal "compression" so to speak, even...
