I am thinking about adding Vance and Hines Slip On Exhaust to my 2007 Heritage Softail Classic. If this is the only modification that I want to make now, do I have to add a tuner or can I just change the mufflers? Thanks.
I second that. Only with muffler change may notice drop in fuel mileage. This is caused by excessive use of right wrist while enjoying sound of your bike.
