well i'm the moderator so i answer lots of questions.
i'm not the only one here, there over 300 members... or
did you mean why only 1 pipe ?
there may very well be others but i only know of one that fits the R50x.
with the other TGBs (keywest, 101,sunset) there are 2 or 4 manufactures
that make pipes that fit.
but they don't fit the R50x.
if you decide to buy some other pipe let us know if it worked on your r50x
