Diy de cat header's

Hi all
Was wondering if anyone has ever modded the standard R1200S headers and removed the cat in one way or another?
Obviously there must be a performance gain, but do de cat headers fail an mot?
Any thoughts appreciated

Hi BW,

Don't know about a DIY decat - no doubt it would require a bespoke 2-into-1 section in its place. Are Y=pieces available, as per 11S? You could replace the entire header/cat assembly but....kerching!

AFAIK it still is not a requirement for a bike to have a catalyser fitted for MOT.

What about this option?

Send a mail and see if they do headers alone, or just go for the whole system........... Cheap enough, I think?

What's the € just now? 1.40?

Gotta love an exhaust system with right angles in

Struggling to justify the price of aftermarket headers Mike. thought I might be able to or get someone local to Fab me up the Y piece. Was wondering if the finished result would be advantageous, what with the link pipe up front on the standard headers.

Just noticed that - not clever.

But - the complete system appears to be better-designed, and still a good price.
