Would I have to get my new bike remapped if I install the S&S Mk45 mufflers?
Larry N on Nov 22, 2016
BEST ANSWER: Anytime you make an exhaust adjustment there is the possibility that re-jetting or re-mapping the fuel system will be necessary. Please contact S&S for further and more accurate information on what this item requires to optimize performance upon install.
