As you could probably guess, failures in my field are shall we say rather permanent & extensive.

.050 321 ss with .050 spun end plates and .049 tail pipes remember the major advantage to 321 over 304 is the TI alloy and the added capability to deal with heat and combustion gases thus the reasoning for general avaition to use it in ALL of their exhaust systems when piston powered. when jet powered well thats a different story where inconel and TI are the exclusive products

Current project 73 914-6 Gt project rusteration 2.4 ,heat exchangers, oil tanks, etc
