I'll post a pic tomorrow, but yes I used a 5" (I think) stainless hose clamp, but before mounting it, slipped some black heat shrink tubing over it to clean up the look. The heat shrink technique is a trick I picked up here on FABO. The tubing fit so snugly that I didn't have to shrink it at all.
It's 1 louder!! Er, I mean, faster!
