Before bolting on the exhaust for good I decide to fabricate the small grommet shield for the manifold pressure hose firewall passthrough. This small task will prove more complex than expected despite following Tony Bingelis' instructions.
First thing is to mark the stainless steel sheet using some steel tube.



Then I press a socket into the tube to create the shape.



This is the result, the sheet will then be flattened, cut and drilled.



Stainless steel is not that easy to work but I also have some space problems for the screws, so I had to try a few times before getting the result below.



This is how it looks once installed on the firewall. I will put some sealant before final installation.



This is the cabin side, the screws are barely visible and will be shortened.



I then begin to work on the exhaust. First all the parts come off, then the joint and the studs are covered with antiseize paste. The picture shows the muffler parts inside the exhaust tube.



This picture shows the joint with the three bolts and springs holding the flanges together.



Some bolts need some tools and creative thinking to get torqued. Here I have a socket (1/4" because bigger won't do), a universal joint, an extension and then the torque wrench.
