[Engine] Emptying out the cat converter, benefits?

[flashBE]

I'm planning a large service on my 1.6HDI 75hp (9HV DV6BTED4) and was thinking about emptying the catalytic converter for perhaps a bit extra torque or some extra ponies. I have luckily no FAP, or DPF, name it as you wish.

Is this something that gets done quite often or rather not? Do or don't? Will the benefits be worth the trouble?

Thanks in advance
