Exhaust Stud Thread Pitch?

Can anyone tell me what thread pitch (size) the exhaust studs are? These would be the studs in the OE midpipe/cat that would mount it to the downpipe or cat back.

Thanks!

Anyone? It's gotta be M12-something.

I believe they are m10x1.5

No, they are definitely M12, and NOT M12x1.75. Maybe M12 x 1.5.

They're M12 fine pitch. Not the regularly available M12(-1.75). I don't recall if it's M12-1.25 or M12-1.5, just measure them.

If you still need this info pm me. I've got a thread pitch gauge and a pulled engine! I will probably forget to check by the time I get home, so just pm me a reminder.

I just verified with a spare main cat that I had---- they're M12x1.5 :icon_tup:
