Genset exhaust (venturi/genturi)

[Keith Strehle]

A while back at the Quartzsite Rally I saw a genset exhaust venturi
arrangement that I believe belonged to Ron Faubion(sp?)

I looked at the Camping World version but was not impressed. I believe
the one I saw at Quartsite was all metal and the venturi was about
shoulder height?

Are there alternatives to the Camping World (Camco) version?

Thanks, Keith
