I've got a DC header with 2 1/2 inch cat, I recently had to change my headgasket and when i took the header off the original just crumbled away. So I went to autozone and purchased another but it was metal. When I put it on fitment was **** and sounded like open header.

My question is which gasket should I get? I think a rubber one would do the job a little better but dont know if a certain model comes with one or not (S200, ect.).

 

You can go to Midas and ask them for a stock doughtnut gasket and see if have any rubber ones or honda the part number is 18229-S01-X11 GASKET, FLEXIBLE EX. (51MM ID.- 64MM OD.)

 

Thanks for the input! I know my header/cat are bigger than normal is there one I can get that might fit a little better?

 

The gaskets are based on diameter of the exhaust, you'd have to measure out the side of the Inner and outer....i.e. 51MM ID.- 64MM OD. the inner will be the header male height and the female exhaust height on the inside of the pipe.
