exhaust donut gaskets

i need to replace my gaskets around my cat and should i get them from subaru or another place, what other car uses the same gaskets

They are the same as some nissans. I know napa sells them, but you have to have them look it up for a 1994 legacy because their parts catalog doesn't list them for SVX

I asked napa about the legacy and they didnt have it, he said just bring the gasket in for him to match up with another one. my issue is getting the gaskets off in 1 piece :S, either that or i pay 70 at subaru for all 3

anyone know of a way to pry off the donut gaskets while keeping them intact?

so ya screw it i aint paying subaru $70+ for the gaskets, i just picked up some RTV ultra copper for 9 and just put a ****tonned on the existing gaskets. Good as new, redneck patch job but hey its a saver

RTV in the exhaust eh? Not worried about fouling the O2s? I would still consider the NAPA gaskets, ive had good luck with theirs since for the most part they supply corrugated metal crush type instead of the ceramic gritty ones..... although ill be the very first to admit, working with most exhaust connections is a PITA. I used to have to redo my manifold and flange gaskets every 6 months on my old 4-cyl toyota truck (in HS, before I knew what machining was) which are notorious for exhaust leaks from there. I just hate that pptpthphhtppthp sound on an otherwise good running engine

why would it affect my O2 sensors? its on the gaskets around the y-pipe cat which comes after?
and i called napa and they dont have a record of it. they dont even have 92-94 legacy echaust gaskets in their records, but they have records for an XT6 lol

Errr I meant the cat

yeah.... the cat.......

For some reason I was still thinking about my toyota exhaust, it had a single O2 after the Y pipe.

hi exhaust dounts for svx ,the rear one is bigger than any early legacy ,the front 2 i beleive are close to 1.8 impreza ,the sping bolts are longer but i use legacy ones ,rtv is never smart on exhaust any where silicone can pass through a 02 sensor it will ruin it
charlie,

which is why its after the seneor, good news is that its sealing but the cat is still giving off a rattle. anyone know what could be causing it?
