As i guessed, the carbon scorpion had gone. I took a punt on a S/S Venom can for £25 with a link pipe for a VFR 800 FI. Missing a strap tho. They have a SS Venom with link and strap for a (I think) 2001 R1 too and another Venom SS, but it's bolt on - I think for a GSX-R 600. Both £40. All are Not for Road Use stamped and bafflesless.
Had a look on the bay and see that VFR link pipes are over £25, so worth a punt. Anyone got a K3 link pipe or strap

? Should sound better than my aluminim road legal can (though it has cost an extra £10!).
