I just bought a 91 from a state where there are no emissions tests. The owner had replaced the catalytic converters with test pipes. I need the cats to pass emissions, so the owner sent me the old ones along with some ring/flange thing. What I'm confused about is that the ring sticks way out above over the other triangular flange. Is this correct? Does the ring compress when I fit it to the exhaust system to form a seal?
