Catalytic Converter

[SIckEM1]

Tomorrow I'm taking my civic to a local exhaust shop to hopefully fix the rattle coming from my catalytic converter. I was looking under the car and noticed that the front two bolts would probably be reusable but the back three are pretty rusted out. I'm planning on purchasing some replacement bolts just incase the old ones can't be used. What are the size of these bolts?

The local exhaust shop should have them. Just make sure they use the springs that's over the bolt. Reason is we don't have a flex pipe and those allow it to flex a little without breaking.

I got some nice stainless bolts for mine and went through and had them all cut out and replaced so I wouldn't ever have a problem again

and if anything get a flex pipe which they are very expensive at all
