Removal of expansion chamber.

Just curious to know. How much of a difference does it make post removal of the expansion chamber. Is it worth removing it?

firstly, what do you mean by expansion chamber? If you are talking about the catalytic converter, it is being discussed in This thread.

I had the same question, i guess it is supposed to improve the torque.
The only reason am thinking of this option as it is low and touches the speed brakers...

I think he is talking about FFE.
FFE has expansion chamber to boost the torque.

No, not cat con. My cat con was removed long back. I was told that once you remove the expansion chamber too, there'll be a decent increase in torque and initial. But some people are saying not to remove it as it will boost the initial but result in a drop in higher bands.
