Since the AMT '55 kit has moulded in exhaust system and I'm using the '66 Nova Pro Stock chassis, I needed mufflers and pipes. So, I made two mufflers and will be using the 2mm aluminum "wire" for the exhaust and tail pipes. Another first in my modelling history.
Below are what I'm calling a mockup so far. I haven't decided to work on bending the "wire" to bring the tailpipes out the rear or go simple and exit the pipes to each side in front of the rear tires.
