why not replace the heavy stock muffler - 7kg [over 15lb]
with a good slip-on of your choice, with a range of
potential sounds and db reducers available..
that way you get a real improvement in power/weight ratio,
with a lighter [better] quality muffler which enhances your bikes
design and lines etc, without compromising intake integrity..
you can always store the stock muffler/cat for later sale, or etc,
thus keeping its value, plus the value of the slip-on [if sold]..
[your motorcycle of course,, just another alternative]
