Exhuast gasket
 

Where is a good place to go to get an exhaust gasket?

I think it is the standard flange as it is the same size as my prodrive back box.

It is the one inbetween the backbox and center section.

Just fitting a backbox? It should be 2.5". I ordered mine online via ebay I think, really cheap. I would suggest a oem cone gasket if your fitting a centre section to your downpipe.

My center section is 3" and my back box is 2.5" but the flanges are the same. Flange is the same size as my Prodrive backbox as well

Have had the card type ones before and they keep blowing.. :(

Get it from import car parts, they use proper Subaru gaskets and are very cheap compared to main dealers.
