Jim,
I've used both the SDR pipe and normal PVC up to sch 120. I then turned to
using PVC Heat Duct pipe. It has thin walls and comes in diameters up to
at least 24" which makes larger secondaries much lighter. Originally, I
had some concerns about it being gray (possibly due to carbon in it),
however, although I didn't specifically measure it, I did not see any
noticeable difference in performance.
Here's a link to one company that sells it:

Best regards,
David L. McKinnon
