I am replacing the passenger side catalytic pipe, the whole pipe converter from exhaust manifold to the clamp towards the muffler.

Does anyone know the size of the nuts and thread that secure the pipe to the exhaust manifold?

It will really help before I take it apart to get some in hand, just dont know what they are, mm / thread size...

Thank you

 

Ever get an answer on this? i am looking for the sizes or part numbers to I can put mine back together properly.

 

I haven't gotten anything and was hoping to replace my catalytic pipe next week and be ready. The only thing i can confirm, at least for my car, i have stock exhaust and the sleeve that connects this pipe to the muffler , the one with the dual clamps is 50mm.

If anyone knows the nuts/bolts sizes on the manifold to catalytic pipe it would be of immense help in having some replacement parts on hand , as we all know those nuts usually round off as they are rusted or corroded after a couple years.
