you used to be able to see & order them at rvmracing.com, but it now is just bringing up wheels/tires. Their price was around $180 & they honestly are pretty nice..came w/hosetechniques hoses, supplied clamps are so/so. Also, back when I bought mine their online store was NOT secure so be careful. Might be best to call, but they aren't the most polite people in the world:( As far as those other pipes you mentioned on ebay, I would stay away from them. The pics alone look like @#$#. Scott's would be great if you don't mind spending a little more.
