Exhaust Gasket P/N?
 

I bought an exhaust gasket to go between the exhaust manifold (Wagner Header, actually) and the first cat.

The Mazda guy gave me p/n ZM-01-20-520.

It looks different than the flat copper gaskets that are on there now...

This one is silver and is two gaskets spot welded together and has an outline that is not round.The inner is round - the outside has a big 'tab'.

Did they change/imporve the design?
Is this a good gasket for me? Or do i need the flat copper gaskets?

Thanks!

Never mind... I found the manual - it is the correct gasket.
