VP TMD 22 muffler

Paul Osterberg

I do some services New elbow, cleaning the heat exchanger and turbo etc. My question what to do, if anything with the Stainless steel muffler? I have seen that some have had corrosion dammage is that common? Shall I replace while at it or will it likely last another 5-10 years? now 20years old.
