Anyone replace the stock exhaust with an after market pipe? I will be getting a pipe also, just don't know which one yet...
Does changing pipe affect your MPG?
A slip on will increase the amount of air. More air the leaner it will be and actually your MPG will slightly increase or be just the same.. Be careful not to run too lean!!
Once you add a programmer you are adding fuel then you will be loosing MPG.
MIVV Exhaust
A lot of customers ask if they will need to re-map their bike if they install a MIVV pipe. MIVV pipes are designed to not require remapping if you leave the dB killer (baffle) in the pipe. However, for optimum performance on any aftermarket exhaust (not just MIVV), you will want to re-map or tune your bike. Because most aftermarket exhausts allow more airflow, it is common for a bike to run slightly leaner than stock after installation. For most bikes, this is not a serious problem.
