Not sure if this is the spot to post...

Already have 3" intake tubing upgraded on the truck. This includes the all the IC pipes/hose and intake manifold. The problem I have found is that the thickness of the tube does not hold up. I found this on websites like intakehoses.com etc. Anyone know where to get thicker 3" intake tube? The 3" OEM stuff is perfect and holds up well to clamping. This other stuff caves in on itself.

Thanks
