You might not HAVE to re-jet, but today's bikes are already very lean from the factory, and adding a less restrictive exhaust just leans it out more. It's a PITA to re-jet a Vulcan, but there are significant gains to be made by doing so when swapping out the exhaust.
You should be able to search jetting, and find out what people are doing.

Cobra Pipes for my VN750
I just ordered Cobra mufflers for my 2006 Vulcan 750. The guy told me I may have to re-jet the carb. Should this improve my bikes performance... What do you think???
