scorpion exhaust doesn't fit to manifold??

[Miris325i]

Hi, as a title i bought scorpion exhaust system for my e30, but when i tried to fit to my s/s manifold, they don't fit properly.

From picture left pipe is fine...gonna have to use a circular ring, but what about right one? they are not "too tight" for use exhaust clamp, if u know what i mean?

Any advise please?

Looks like you need the exhaust gasket rings, not sure on the scorpian ones but on my 2 piece system it was blowing badly as the gasket ring had disintegrated.

There about £7 from the dealer. I couldn't seem to get them anywhere else.
