No. The ball and cup should seal together themselves. Not sure if you could even get a gasket to work in there.

Well i know the auto part stores sell some kind of donut gasket, looks like a giant o-ring with beveled edgesmade outof graphite. i dont have any in mine, someone told me about their exhaust and how they did it and they said they used them. Just curious, never heard about that before.

No gasket on the ball s.  Just make sure they are square against each other and they will seal fine.

The donut gaskets sold by exhaust shops are for a manifold with a flat . There's a ring in the center, you place the donut gasket over the ring, then bolt a cup  onto the manifold and the gasket makes the connection. This graphite "donut gasket", by the way, is technically called an "Exhaust bearing" (the next time you see somebody teasing somebody about "blinker fluid" and "ler bearings" you can let 'em know that exhaust bearings do exist). It's designed to allow some movement between the pipe and manifold, and the pipe is usually attached with spring loaded bolts. It's common in GM vehicles. It's also a common failure point.
