I just bought a nice 2005 FJR1300 and it had Two Brothers mufflers and a Dynojet Power Commander III installed. It seemed to work fine but I restored the bike to original.....it came with the stock mufflers. And I have a larger aftermarket windshield too....forgot to take photos of that. Its all for sale. Mufflers look a little aged - see the photos! and the Power Commander comes with an instruction manual. I bought it from the previous owners widow....so I have no idea how the Power Commander is programmed. But it certainly works. Got this stuff on Craig's List too.
