Hey guys, i recently bought a 90 Tsi AWD w/ an engine from a 93. Well, i'm here at my house in the middle of my Big 16g install, and the ring that is inside the exhaust manifold where all 4 runners come together fell out and it was extremely deformed. It's oval shap instead of circular. Well, my question is, do i need that ring? I really don't want to put it back in like that, and i live quite a long ways from my local Mitsubishi parts house and don't wanna drive that far........
