I took the muffler off and took a long drill bit and just kept drilling holes in the desicant till I could break it into pieces and pull out the chunks. You have to be careful not to hit the oxygen sensor. Took a couple of hours to get it out. Runs cooler and that's about all I can tell. Might...
I have the Vance and Hines on mine and it has a low deeper tone. I also have gutted the cat and it sounds different with that. Runs a little cooler too.
Mine does that too. After I put a aftermarket silencer on it it is not as noticable. I think it is hamonics from the engine and frame. I have a 13 too. I am 59 years old and ride a Goldwing also. I love the FZ8.
58. Will be 59 in september. Just put a Vance and Hines slip-on today. Think I will like it. At speed not much louder than stock. By the way I really love this bike. Also ride a 2012 goldwing.
Not much luck with windsheild. Bought Givi and it is not much. Made one work from Super Tennere. Lot better just get a little helmet noise. I ride to work mostly freeway and the windsheild helps alot.
