This is the only Gasket at auto zone that specifically says cat-exhaust gasket(steel).
Others are under "Exhaust flange Gaskets" and are composite materiel.
Im confused on witch ones to get.. they also dont specify the hole diameter?.
Looking for 2.5'' , Gasket after the cats.

 

Exhaust gaskets come in several varieties:
3-material sandwich. Generally metallic material on the outside with a flexible material in the middle. About $10
Cardboard or paper. Cheap. $3

Visit any auto parts store and ask for a 2.5 inch gasket.

 

yeah i noticed that, just wondering if the "steel" one in the link is any good? or should i just get composite?.
Googled some gaskets and came across graphite kind too haha...
Not looking for anything fancy just as long as they work.
Even ran into conversations on google about people cutting out cardboard for there exhaust gaskets haha.
Thanks for the reply.

 

Composite is nice because it crushes and seals. Potentially filling in imprefections. Pure metal is usually used on head to header or turbo gaskets.
