Exhaust ring join gasket

[2bmws]

Hi guys hope one of you can help I've bought 2 of these now, and they both are too big for my exhaust, I've got a 1.9 so hoping someone can recommend one that will fit

please

I've tried my best to measure the outside diameter of the exhaust where it slides on, and cant find my micrometer so used a tape measure and it's either 2inch or a little bit more than 2inch across, so on ebay ordered both for less than 1 that's suppose to be for a bmw

Just for anyone whoever has the same problem as me the ring was a 2.1inch exhaust gasket conical joint
