Need Help, Ark Dual Exhaust

Hey guys quick question. I received my ark exhaust system and ran into a small problem trying to remove the stock exhaust. I can't seem to get the stock exhaust out of the rubber connector that keeps the exhaust connected to the undercarriage. Has anyone had to deal with this that may be able to give me some advice?

Thanks,

youve taken off all the bolts and such?
get some wd40

try using a screwdriver to work it out
