When I had my exhaust made they made a gasket and a flange that fit up to the OEM DSM o2 housing of my 14b. I keep blowing out the gaskets. This time they put 2 gaskets instead of one and its held up better. But I've busted through again (not as bad this time). So my question is where can I find a OEM gasket besides mitsu? Or is there anything I could try myself?

 

Get rid of the gasket in between. If both surfaces are flat, it shouldn't leak.

It's just like the Turb/Manifold gaskets, they leak all the time too.

 

i'm having the same problem, i think i'm just gonna stop being lazy and go get the mitsu gaskets from the dealer.
