That is now coming quite common now that EURO 4 has come in..
the idea is to split the exhaust charge so theres not one big cat..
it's easyer to have 2 smaller cats 1 in each muffler..
also one of the reasons the big singles are on there way out..
too much exhaust gas to deal with at one time when there is limited room
on a bike for the cat... With a twin the exhaust charges are smaller and
easyer to deal with... Is the main driving force behind all the new twin cyclinder
ADV bikes that are starting to show up....
It could also be the end of some after market exhaust companys as there is a few euro
countrys that are making the cat part of the yearly inspection... So why spend money on a exhaust
if it still has to have a cat to pass the inspection....

Also it looks like the japs are going to stop making the smaller scooters as the componts
needed to make them EURO4 compliant make them to exspensive & rob some
of the what little power they already have... Honda are making noises of cutting
everything from 100cc down..
