Wraith - Front Exhaust Expansion Chamber
Supports - WXA-37.
Mileage 9,961.

I am forwarding to you two tubular supports of the front expansion chamber which have broken.

In my opinion the bottom flattened ends should be longer to allow for increased springiness. As it is, the change of section is too short in length to allow for the movement of the exhaust system.
