BRZ Donut Gasket same part as WRX STi Gasket?
 

Like the title says, is the OEM donut gasket that connects the front pipe, the one with the second cat, to the mid pipe the same as the one found on WRXs?

The Accelereated Performance Exhaust, which I've had a few issues with recently and in the past, didn't require this gasket, but the Invidia exhaust I'm picking up does. Hopefully I'll be able to find it at home but in case I don't, I need to pick it up somewhere.
