Catalyst question.

[SO•Audiojack]

By the way, I don't know how efficiently VW develops their exhaust systems for the base models but if you remove exhaust restriction from your STOCK car it might actually effect your torque negatively due to loss of back pressure.

(Again, I don't know if Volkswagen has tuned their engine management to take advantage of the restriction that a catalysator creates but I'm assuming so.)

In a car like yours, a daily driver and all with no real excess power or torque to speak of, I would say the low end torque is much more desirable than pure peak power output.

And to be honest, I would only remove the catalysator if it was in danger of getting damaged by raw fuel or excess heat (antilag, ignition cut rev limiters and launchers etc. as I mentioned before.)

Just get a new cat from Biltema or something and you will atleast pass MOT inspections with your car...
