I hate to be thought of as a Killjoy...........BUT I thought that a Catalytic Converter was added to the bike in order to reduce the toxicity of the emissions from the engine.
On that basis, it seems irresponsible to remove it and subject all around us to pollution and possible health risks.
As someone with Asthma who used to work in Central London, I can vouch for the detremental effect of exhaust fumes.
Why not just enjoy what is by far the best bike I have ever owned in 30 years!
