Question about donut gasket
 

So I have a 2001 civic dx and i purchased the obx 4-1 header. My problem is that it is leaking where the header attaches to the catback. Most headers have a donut like gasket. This header has more of a sheath washer placed inside at the bottom that wiggles around a bit. The car is louder than id like it to be. is there any gasket that will seal up this leak? its a 2inch diameter hole where the header lets out. I saw this http://cgi.ebay.com/ebaymotors/OBX-D...Q5fAccessories
but i dont think it will fit in my header because its 2.25inch. Any advice?

i think i might have one in my stuff...bump this thread i will look tonight.

do you know the part number for it or what it is called because i have not been able to find in any online stores.

Enter your VIN here.

dont they make a compound that you can use to make a "custom" gasket.
