Can someone tell me the exact size (diameter) of b210 exahust packing between manifold and exhaust tube
The opening into the exhaust manifold is 1-1/2". The original exhaust tube was 1.5 inch also
I've never seen the type of packing shown on eBay, but I have seen where the original exhaust tube has been replaced with a plain exhaust tube and a "donut" packing seal (compression type gasket) added. It is made of an asbestos-like material. It is also 1.5" size

Regarding silencers, the B210 GX came originally with two silencers, 1) a regular full-size muffler and 2) a smaller "resonator". Similar to this:

The joints between silencers and exhaust tubing used no packing, but were welded at the factory. The joint between exhaust pipe and muffler used a slip-fit and exhaust clamp (no packing). Replacement silencers generally use slip-fits and clamps on both ends of the silencer
The eBay gasket is used with a bolt-on silencer (has a bolted flange instead of slip-on connection). It is possible to change the 1200/B210 exhaust pipe to a pipe with flange -- if that has been done to your car then usually a flat gasket would be used instead of the ring gasket shown on eBay
1990-1993 A12 flat gasket with 3-bolt exhaust manifold

1994 A12 ring gasket with 3-bolt exhaust manifold (steel ring is approximately 1.75" I.D., 2" O.D.)
