Hello all I'm going to change the exhaust pipes of my beater this wk end and I have a noob question for someone who is familiar with exhaust gasket. In fact, I notice the gasket between the cat and the A pipe has one flat face in one side and a "round" face in the other side (link). https://www.amazon.ca/Walker-Exhaus...
AFAIK, the flange from the cat has a flat face. As for the A pipe, its flange has a circumferential flat groove (link).
My question is how should I position the gasket between the flanges. I haven't disassembled the exhaust pipe yet, so I have no idea what is the old gasket orientation. Furthemore, the old gasket is probably rotten out and it will be hard for me to determine its orientation.
