Newbe muffler query
(English is not my main language so excuse grammar/spelling/syntax etc)
What I understand is that in order to clear the M.O.T I need to remove some kind of parts in the rear end of my muffler.

What I donīt understand, is how will removing parts make my bike more quiet?
Please explain.
