yea good point I thought about that too but the problem is that I have to have the pipe geometry follow exactly with the curved path so my only option left is to do an extrude edge causing it to recreate the polygons and UVs. the reason it has to exactly follow the path is because circular rings of vehicles will be following the same path and if the pipe is off just by a bit, the vehicles will look like they are hovering off and on the pipe. Even if I used nonlinear bending methods and tried to do the bending as close as possible to the path it would still look off.

make the pipe straight. texture it. THEN bend it.
