Not as long as you leave intake stock.

I put on cobra slip on exhaust and changed to K & N air filters (not pods) and all I needed was an a/f screw adjustment.

On any carb bikes I ever owned as long as air box was stock you could could just run header pipes and no rejet. More power comes when you have more air coming in and less back pressure. Other wise you are just making racket.
