Its great that you can get this done, but Riverbank really is taking advantage of the situation. £60 labour to remove the end can (2 bolts and 5 mins off and on) and wedge the cat into the end of the link pipe is a joke. On top of cost of the cat and then the farcical £175 test fee?!.

So before spending all the money, do as Gnasher suggested and give Yamaha a call to check the emission figure for your bike, if its under 0.15 then all it will cost you is £60 for a Certificate of conformity which you then upload along with a copy of the first page of your V5 on the TFL website -

You dont even need to put you full/real details in, as all your doing is getting the bike onto their database to prove the bike is compliant (see attached) after which I see no reason you can't delete the account.
