XRs Only Exhaust for XR 600

If I purchase an XRs only exhaust system for my XR 600 would I need to change the jetting on the carb?

usually changing from a restrictive exhaust on these bikes,going up 1 jet size is necessary,but depends on how you are jetted now.....take a look at the plug....if it`s black now then don`t go larger,if it`s light tan colored,then maybe....
