Completed plumbing. Some of the tubes are not as described in the plans, the plans won't work. Now need to remove it all and the fittings.
Started making floor insulation. Consists of two layers of 1/4" SuperSoundproofingf foam mat with a layer of tin foil glued between sheets. This will be used on the bottom since the exhaust pipes are a major source of noise. The sides will be one layer o fjust the foam. Firewall will be something else. Purchased some material to make templates for the firewall insulation.
It is very easy to do this while the side skins are off. Some insulation can be installed before side skins. Plumbing was easy to reach in the tunnel. With the skins on, you would need to climb in or put it on the floor and bend over to install.
