I have recently put this system together on my bike and am looking for opinions on the "noise reducers".  Did you install the the little disk with holes in it into the inlet side of the muffler?  Also did you use the Stainless Steel Phallus in the outlet end of the Muffler.  What were your results.  Did you notice a decrease in low end without these items installed?  Do your neighbors hate you??  Any advice or opinions would be GREATLY appreciated.  Thanks!!!

Not sure, but I think (just think) member "the Ron" might have a similar set up. Anyway, he lost quite a lot in the lower end and solved it with a Power Commander. You could check his posts to see if I remember correctly and, if so, send him a PM.

Good luck!
