Anyone know what size the bolts are that connect the cat to the y-pipe?

Thanks

I dont know entirely right offhand but I believe they are metric with a threadpitch of 1.5 and I THINK the diameter is 10mm. I can take a look when i get home (will be about 3 hours)

 

Well if you can find out you'll be a great help.

 

Anyone know?

 

M10x1.5 with a 15 millimeter head and integrated lock washer. They also appear to be made out of solid rust, however because of the high price of rust due to the rust shortage on the moon i'd advise getting stainless steel, I forgot how long they were but I'd guess ~3 inches? Hold the flange up to it, measure the distance and add about a half an inch.
