SSie downpipes

[twpd]

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.
