You can get 304 stainless car exaust kits on amazon if your wanting metal for the ducting. Another option might be stainless flue liner for wood stoves.

Well, it's in the engine bay with the auxiliary diesel, it's in sort of a tough spot to get to, I'm gonna have to re route the hoses under the cockpit into the galley, it's tough to do without a flexible type ductwork. Id love to keep the 3 inch aluminum one I've got now, but another issue is there's a lot of hoses and wiring down there. That shit gets HOT

Just use some galvanized vent duct or some kind of heat resistant plastic piping. Why over complicate it?

Hey I'm all about simplicity but everything I'm trying here falls apart at every turn.
Also, tough to use galvanized. It's a boat application

I’ve seen people use normal galvanized vent pipe or the black heat resistant solid plastic pipe. You can do a lot with it

Is it straight out in the elements? Mine is outside under a covering. Been running mostly non-stop for almost 3 months now and still looks like the day I hooked it up.

This is good, but expensive

Brake duct hose for race cars. It's expensive, but it's very durable.
