My method usually is selecting the correct ID to be a tight push fit on the muffler outlet, sometimes adding a plastic tie.
Two places I did it differently.
The "Tiggekitty" has the tubes glued in the firewall with RTV silicone.
My "Diablo" with a K&B 61/Pitts muffler kept blowing them off, so I drilled through the stacks of the muffler and stuck a piece of wire through the stacks and both hoses. No more lost hoses.
