Primary Pipe diameters for XE exhaust manifold
I have calculated the appropriate primary pipe diameters for my XE exhaust manifold (thanks Mr Ashcroft! ) and they do concur with the diameters on
manifolds that I have used in the past from BTB/SBD.
The issue this time is that I am making my own manifold and the economic way for me to do it is to use 316 stainless hygienic
tubing................the problem is that I can only then choose between 1/2" increments.
For the primaries 1.5" is too small, and the next option up is 2".
The question is....will using 2" primaries AND secondaries lose me a lot of mid range torque?? It would certainly make creating a nice 4-2-1
manifold easier as I will have to buy less pipe!! The final pipe will be 2.5", which apparently is correct for 200-220hp, and usefully fits the
Caterham R500 carbon silencer that I aquired.

Would they be mandrel formed? If so then that does sound interesting, I can certainly get straight tube no problem!
