I've been seeing threads about a split flange for repairing the rear of the cat. converter. Where's the best place to get one, and how do you measure/order it? Thanks.

are u sure its the flange? mine was only the gasket, i only changed the gasket and bolts and that was it... total cost was $15.00 at the dealer

I have found a split flanger on my previous subi... it was slightly bigger than the pipe, so finally it broke off the rest of original flanger and connection was lost. I went to autozone and to my suprise I got slightly smaller there -- it matched perfectly and I never had problem with that one (though it got rusty very fast)
