SSie downpipes
 

Does anyone know where to source some alternative downpipes? I've just dropped the pipes off one of my 800's and they look ever so restrictive around the collector area - I can't believe they are helping the motor at all.

If no-one knows of any supplier I'll get some fabricated up locally but, I daresay it'll cost a fortune.
