What PSRU do you have in there now? BTW have you seen Mike Wills lately?
Is he still working on his fine rotary powered RV4?

Here are some pictures of his cowl for the new guys.

Also my hangar neighbor John Lynch can 3D machine a high density foam cowling buck
directly from a Rhino 3D drawing  for you if you have more money than time.

John did the Nemesis Nxt buck.

Paul, that looks like two straight pipes with a slight downturn for the exhaust. It makes my ears hurt just thinking about it!

Those are two glass packs on there. Remains to be seen how long they will last.
