Exhaust pipe bolt size.....

Specifically the pipe between the y pipe and cat that has the O2 sensor. Mine are extremely rusted and I want to take that pipe off to change my rounded off O2 sensor. Yes, its gonna suck. I need to pick some up beforehand.

I think they are m10x 1.5 mm thread pitch but someone else may want to chime in..

No stock exhaust available unless I pull one off of a pathy in a parking lot somewhere, and that might be misunderstood...

Yea my original plan was just pull the entire pipe from pick n pull. But it has to be a 94-95, and then it turns out my pick n pull just destroys most of the exhaust anyway pulling the cat. I need to buy a 300 dollar A/C commuter car for moments like this.

Oh, wait, this one with the pre-cat? what bolts are you talking about? The holes in the flang opposite end of the cat are 11+mm, and the bolts for the flange onto the cat are pretty damn rusted. Do you want me to try to pull one and if I can get them out, do you need the pipe? I was just holding onto it incase I had issues passing smog with my custom exhaust.

I don't have a pre cat. But yea, the pipe with the O2 sensor.
