Need help with install of true duals, got them 2nd hand, no instructions... Can't figure out how the left side fits? It appears the factory bracket is in the way. I can't get it around the bracket so I'm guessing it needs to be removed first? Does anyone remember or have instructions in a pdf, cant find any at V&H site. I may be missing a bracket they supply with this exhaust, if I remove the factory bracket the only support would be at head and the rear two bolts can this be right? Thanks in advance for any help.
