Nut/bolt size?

[Down2Ride]

What size is the nut/bolt that connects the ball joint flange from the downpipe to the exhaust? Truck was bought used and I know it had a tuner on it. Seller must have forgot to bolt it back up. Imagine that! The nuts are missing from the bolts! Just need to know the size so I can secure the exhaust to the downpipe. Hope it didn't mess anything up! Thanks (in advance)!

Do you mean the Y-pipe to the exhaust manifold?

The front of the exhaust pipe with the filter is disconnected. The bolts are there (connected to the flange on the exhaust), but the nuts that go on the bolts that pull the ball joint together are missing. The exhaust is just loose. Right where the cross member goes from frame rail to frame rail.

Just remove one of the bolts and find a nut that matches up if it's easy enough to do that.

I was gonna do that if nobody could tell me the size. I'll have to knock it out of the flange on the exhaust.

M10x1.5. Finally got it after a little trial and error.
