A while back I bought a cheap exhaust system from ebay and it was basically an all-in-one package from header to muffler including gaskets and bolts.

And well.. I didn't tighten up a couple bolts all the way and 1 flew off while I was driving and it opened up enough to burn out my gasket. (It took me forever to find the right bolt and nut for it so it had time to burn it.)

Now that I have the bolt and nut, I need a new gasket but can't find one ANYWHERE on the internet or eBay. Some help maybe?

It looks like this:


Mine is 2.25 inch and looks exactly like that.

TL:DR, Where to find 2.25 inch gasket like the one in the pic.

 

Trace and go to Auto store where they can find something to match. That ngoes between the downpipe and header/manifold.

 

Sometimes you will see a slot to fit a crush-ring like one of these in there.



And occasionally you will see this, but mostly for catalytic converter mount:

 

I tried, they had nothing there that matched what I need. They have some do-it-yourself gasket maker there but I'm skeptical of it. It feels like it's made of compressed cardboard that you cut out.
