I would think it would depend on what type of exhaust your replacing yours with.

Without more information its hard to say. Are we talking stock pipes, aftermarket, what brand, two into one. What exactly?

If the pipes are aftermarket they are often less restrictive than stock. Less restriction means the engine will run leaner so you will need to increase fuel flow by changing up the jets i.e. higher numbered jets.

Often, you may not be able to tell what you're facing until the pipes are on and you are able to roadtest for performance. If you find the bike is not performing the way it did or it coughing, spluttering or backfiring, you will then need to experiment with different size jets.

It is a difficult question to answer without more detail but if they are not stock pipes then most likely, you will need to rejet.
