Dear All

Can someone tell me the exact size (diameter) of b210 exahust packing between manifold and exhaust tube

thanks

There is no packing (gasket) between exhaust manifold and pipe. Instead the pipe has a kind of tube flaring that seals it



An aftermarket gasket can be fitted, the pipe is 1.5 inch


A12 made from 1990- and newer used a different manifold that used a flat packing (3-bolt flange)

Hi DD

This is what i am referring for

That is a "BOLT ON CAN SILENCER GASKET" for a motorcycle exhaust

So unless you have can-type silencer ...

What is the exact size of your exhaust tube? It may have been changed at any time in the last 40 years ... so measure it. They all left the factory with 1.5 inch exhaust piping

If that doesn't answer your question, can you post a photo of the part of your exhaust system in question?

Quote: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.)
