I think it is similar to the way i decoked my Lawnmower, with a very hot flame (blow torch thingy) and a constant tapping with the hammer. Never done this on an aircraft but really sorted out the lawn mower

Also by heating the plating inside it is working like a catalytic converter and burning away all the impurities, only thing is you gotta do the heating up part. Should maybe try to strip a catalytic converter and build exhaust for my trike and see what the results are
Anybody need a visit on night need some midnight spares

De cokeing 503 exhaust
Hi Guys , this is what I do ,
You need a blow lamp , nice and hot , but not to hot to melt or burn the baffles inside the exhaust- heat the exhaust till itis smoking , nearly red hot and add a compressed air pipe to supply enough oxygen and whalla .
The carbon is glowing , whie smoke , getting hotter and hotter til it all burns out , when it stops smoking , the carbon has been burnt , and tap it gently not denting the exhaust and mt Totax is good as new - I use wynns dash , the whit liquid on my exhaust , it keeps it new and rust free , once a month I give the exhaust a nice wt cout with a 2x4 cloth and whalla its good as new - if its rusted , wire brush it , add a bit of Zebo stove polish and wynns dash - smart man smart , check you ous later the guinness is getting warm , Leprachaun
