My wife just got a 2009 RS, SE5. We are already looking at replacing the stock muffler. When doing this do you have to replace the air filter to a high flow and have the ECM reprogrammed? When I installed Vance and Hines slip-ons on my Harley I had to do this. Has anyone replace their stock mufflers and what brands do ya'll recommend.
Looking forward to hearing from some of ya'll on our question.
thanks
