Exhaust gasket help wanted.

[gsodonis]

Well, it looks like my 1992 y-pipe, precats and main cat have just about reached the end of their useful lives. Since the driver's side pre-cat makes contact with my WRX 5-speed tranny conversion (the tranny crossmember), I'm opting for a new replacement Walker 2" dual inlet, 2.5" single outlet main cat and a delete of both pre-cats.

My question to the SVX exhaust knowledgeable: do I need to order replacement gaskets for the three that are affected?
1. two o-rings between the cast exhaust manifolds and stock pre-cats
2. one larger o-ring between the output of the main cat and the catback

Subaruparts.com wants approx. $5.00 each for the small ones and $15.00 for the large one, but they aren't in stock and I won't have them until late next week.

My local Suby dealer wants $7.20 each for the small ones and $23.00 for the large one. He doesn't stock them either, but he insists that he has never seen these gaskets fail and that I can reuse them as long as I use plenty of high-temp Permatex. Is he right? (imagine that, a Subaru dealership parts room guy talking me OUT of buying new parts).

Your help and suggestions are appreciated as always.
