I bought a used DC header for my DA but it didn't come with a gasket for where the top and bottom piece connect. Can I just use oem ehaust gaskets for it or do I need DC specific ones?

 

You can use any gasket that fits the size of the header.

Top and bottom piece connect? You mean where the header flows into the cat?

 

ok, i would like to see the answer to this one too, cause i have a dc 4-1 on my integra and it has the big donut on the bottom which is worn out, when i go to an autoparts store they hand me this little metal ring that is like 1/10th the size of the donut i need. i even looked through all there donuts and couldn't find one that will fit on the dc header. i'm saving this cause i need that answer too!

 

oh btw, the upper gasket will work just like an oem, the bottom donut one is what i can't find.
