Your image link is broken. If you want to send me the Zard mufflers, I can make something that can work, sure. Send me a direct email; Todd at GuzziTech.com if interested in doing it.If the headers won't reach the Zards with their standard brackets could you fabricate SS brackets to move the Zards about 1.5 inches forward ??
Moving the Zards forward 1.5 inches might make it possible to remove the rear wheel without removing the mufflers.
Happy Thanksgiving.
