With mufflers/heat exchangers we don’t weld the outer shell. If a bulge or crack happens on the outer shell it is time for a full overhaul. With stacks or mufflers overhauls we replace all the material and reuse a part over to make a legal overhaul. Typical used over items are: the floating flange that connects the muffler to the stack, a outer ring that the heat muff rests on for proper heating of the cabin or some other insignificant part like a tab, heat muff stand offs rings that hold the heat muff in place and others. After any overhaul is performed it goes through the same inspection as described above. The stack or muffler will come back to you meeting all OEM specifications and performance of a new muffler or stack. In most cases the stack or muffler 90-95% new 321 Stainless Steel or Inconel material. Our overhauls look and perform the same as new. Overhauls are a much more cost-effective than new and with one part used over the system that was overhauled is your best solution to get you back flying and save money.
