I have a new 2009 XB12XT. I plan on installing the race ecm sometime soon. I'll install the race muffler also when it becomes available. In the mean time I bought a near new extra muffler to mod. My goal is to have a better sounding bike without excessive noise. I first cut it apart and remover the 3 pipes and bulkheads.  I'll leave the interactive valve in place to give the muffler a stock appearance.  I'm installing 3 baffles, the 2" holes will be staggered. 2 will be welded at the jack points and one in the middle.  I have a lot of hot rod experience and I'm kind of copying a Flowmaster 3 chamber muffler, not too loud and not too quite. Before I weld everything up, I'd like to know if I'm on track. Any suggestions? | ||

Appears to be.... tough part is making your fueling system match the flow that the new pipe design has. | ||

Tough part is actually building a muffler that produces favorable power delivery. There's more science to this than mere "sound". | ||

Are you using a spring on the valve? cause they rust quickly and if vibration heat and rust get together the springs shelf life is severely compromised and you wouldn't want it closing on you during a ride. I would tack it in an open position and if you ever need it again just grind the tack off |
