Hi Boys,most cans are real easy to shorten,my only trouble with shotguns that I have is that the inner core is tapered & not straight through like most cans,I'm also worried about cutting them because of rarity of this system,Moggi do you wanna send yours damaged ones down to me & I'll have a go at sorting them possibly buy them of you or are you keeping them for spares,my mate just tried to sell his Tuono factory racing with 3.5k miles & it only reached £4150!,He's kept at the mo but has hardly used it since new
