Mounting axle back exhaust - exhaust gasket?

[firebird1999us]

Was going to finally mount my wagolis exhaust and came across some random blips about a gasket that fits between the flange of the midpipe and the axle back. From the pics it looks like a steel wool donut?

I haven't removed anything yet but I'm assuming I may need a new one because the car has so many miles... autozone has one the said is a direct replacement for $10... the guy said it was 1.92". Wasn't a 100% sure on the stock pipe diameter - does that sound right?

Anything else I need? Does someone make a stainless flange bolt kit?

I'm 99% sure I've got one of the donut gaskets from the Toyota dealership laying around I'll check when I get home. Since I don't have my yaris anymore I don't really need it. I'll PM you.

Randomly does anyone make a stainless screw package that I can replace the stock bolts with? They look a little rusted and, considering the factory parts are a bit pricey and I don't think they're stainless, I'd rather pay for something that's not going to corrode!

I've ordered mine off of rock auto and have noticed that they don't seems to corrode nearly as bad as the oem bolts.

Only difference with these is that the bolt is separate and then you put a washer on, then a metal sleeve over the bolt and finally the spring.

The one bolts have the sleeve and washer build into the bolt. What ever you do make sure you cover everything in anti seize before installing
