Carbon can's?

has any one ever had any long term problem's with carbon fibre can's?

been speaking to a couple of ppl i know who said they'd never put then on a big V-Twin again as they found after a white they would fall apart from the constant pulsing?

they had them on an SP1 and an RSV

i've seen many CF cans come apart, not even on big twins. once i almost got smacked in a head with an endcap that blew off a CF pipe on friends CBR. Never ever had, or seen, Al or Ti pipe come apart. i figured it would be worse on a big twin. i went with Ti.
