Haya also did a reasonable job of the exhausts, however, once again there is room for improvement. The mufflers are only half moulded and their heat shields are too thick and extend down to the track guards. Also, the heat shield bolts are too few and in the wrong place. Similarly, the fishtails droop downwards.
Here is the right-side pipe work on Paul Scott’s Centurion. The mufflers are bolted to the track guard brackets, not the track guards sheet metal.
Here is the left side pipe work, including an exhaust for the auxiliary Morris motor.
Here are the left side heat shields, bolted to nubs on the mufflers on the Cent at the Australian Armour and Artillery Museum (169052). There is a substantial gap between the mufflers and the track guards.
I reshaped the mufflers, keeping in mind that the smoker pipework actually comes through the side of the hull directly into the muffler and connects to the fishtails.
I trimmed the pipe heat shields, using them as a supporting platform for thinner plasticard, and added a brass exhaust for the auxiliary motor.
Here is how the fishtails should be on a Vietnam Centurion – bending outwards.
This was corrected by cutting the bends off, realigning and re-attaching with inner brass sleeves to support the joint. I also trimmed the muffler heat shield and added Meng bolts in the correct locations.
