What size Y pipe bolts are used on the stock exhaust system?

I am replacing the clutch and want to fix my exhaust leaks.

Metric 8 x 1.25.

Save some headaches , cut & drill out the old bolt/stud. "Screw the tap routine". Use a 7mm bolt and a nut. You won't have to worry about getting in the same situation again. If it seizes later on just cut the middle of the bolts out and buy new ones.

That does not seem the right size, I am talking about the bolts that connect the Y pipe to the cat back and the bolts that connect the Y pipes to the exhaust manifolds.
