I'm probably the guilty party responsible for the exhaust. I told him about the
company that fabricates stainless exhausts by jigging to a pvc mockup. I think
Ken Powell actually sent him the contact info.

FWIW, Bernie seems to have gotten the cooling drag right on his Lyc RV-6A. It's
faster than most RV-4's & that says a lot.

Nothing wrong with a PVC pipe mockup except you can't get tubing bent
in such small radii.
