Well here is the run down. I been hearing a rattling noise from my exhaust some time now and it has gotten worst. Like a month ago I took my car in to get it serviced at honda they wrote that i was missing two bolts on my exhaust. Today i finally took a look an i saw this. Can anybody tall me what size bolts I might need to fix this. I have a greedy SP2 exhaust if that helps. Thanx

The two missing bolts:


The bolt that I need:

 

If I were you, I'd remove that bolt and get a friend to drive you to Home Depot and ask an employee what size that might be. They have drawers full of various sizes for a few cents. Buy three new ones and replace that one that looks like it's rusting. Pick up some Loc-Tite (get the non-permanent type) to put on the threads while you're there so it won't happen again. Good luck.

Also, vibrations like the one your exhaust system will see can and will loosen any bolt so you should periodically check all your parts to makes sure they're still holding tight.

 

Do you have a gasket in there?

 

I don't think the Sp2 piping has gaskets...they have some sort of interlocking notches
