I recently got a header with a 2.25 inch collector and went through a week of hell tryin to find a 2.25 collector gasket to fit... all the part stores and muffler stores didnt have it in their computer so basically, they didnt have it... cause if it aint in there computer they dont know what they have... any way, it turns out they did have it... Its a fel-pro doughnut gasket... the part number is 60650 and its in their computer for a General Motors V6 produced from 1980 to 1988... I put it on my integra after about 5 other attempts with various gaskets that cause my car to sound like **** cause they didnt seal properly and it worked like a charm... just thought id share this so when people search for a 2.25 header gasket they will find this and not go through what i did...


Footnotes: Need a 2.25 collector gasket for your header? Part number 60650 and autozone or any other parts store should have it

 

What if I have a DC header with 2.5 collector?

 

Then measure the exterior diameter of the collector and the interior diameter of the pipe and find a gasket that fits. Not too hard to figure out is it?

I used 60385 for my DC 2.25 inch collector, it seemed to work however I still have a leak. I'm always having nuts fall off those damn spring bolts. I'll check your gasket out tomorrow.
