Anyone know the difference between the Dyno port big volume pipe and mid-high pipe?Also the difference in the silencers for the big volume pipe???Differences in price between the big volume pipe depending on the silencer used...Also would the silencer I have (fits,old style Aaen,stock,fmf,etc or do you need the dynoport silencer.

Time for me to try one of the "newer" pipes and see how it runs.
