Stock Catalytic Converter - ZR-1 Net Registry Forums

Hello, No problems or issues. While under the 92 Z, I noticed that the flange for the drivers side Cat, well the holes are very much off center and 2 maybe 3 bolts would ever go in, Has anybody else seen this on their cars?

Are we talking about OEM exhaust manifold? Or cats?

just as pictured

Are you saying you have 2 holes not lining up between exhaust manifold flange and thread for the bolt on the block w/ bolts missing?
Both 91 I had and 94 I have now do not have this issue.

Thanks for reply. While im under there today ill get a pic of the actual flange on my car, not as bad.
Just curious if that came out of the factory like that. Eventually the motor is going to be shipped off the Marc h for a overhaul will tackle that then.
