a proper set up will not drone
having fat cannons (cannon mufflers) is all dependant on the barrel size and diamemeter and baffled area
some cannons sound awsome
a good example will be the HKS hi power exhaust
bigger the muffler the more drone u have usually
but a proper sized cannon muffler will sound way better than a dual tip muffler or an oval muffler
also material of the muffler will depend on the sound and also the thickness
it's hard to get a proper sound from an exhaust
but once u get it right.
you wont be going back
