Macchi MC202

Hollow burnished metal exhaust pipes.
These follow the lines of the late Moskit exhausts.
These are made with an electrostatic process (similar process to applying power coat paint) where by they charge superfine metal particles with positive and charge the moulds or what they are spraying on negative and the metal particles are attracted to the mold and eventually you got exhausts.

This process was apparently more volatile or at the very least more dangerous than Moskit had ever thought, as somehow during this process they managed to blow up the entire factory, and the Moskit line died with the factory.
