Educate me on exhaust flame tube inspection

I sent in my complete system and it came back looking like new. As an A&P he doesn't have a repair station so your A&P will need to look it over and sign it off as "exhaust system repaired by welding". I did that as I'm also an A&P but don't have the requisite skills n TIG welding. He's been doing it for many years,

CAP. 

Do you remember what he charged?

As in my previous post above- @ $1600  I had a cracked end plate and missing flame tube pieces,  he checked each riser joint and flange also, generally gave the whole thing a once over. He has a full jig so everything goes back together square and fitting the cylinder flanges.

I put it back together with ALL new hardware and springs including new blow proof gaskets and new mount flange nuts and washers. Good for another 10 years I suspect. His welding is superb! Way better than I could ever hope to do.

He'll have to clean your exhaust system and inspect (measure thickness etc) to decide which areas need replacement - essentially charges for material and by the weld. He's got to see it to give you an accurate estimate. It will come back looking like new.

Who did you use to repair the muffler?Mech told me its gonna be like 3k for a “new” system. Would much rather have it repaired. 

Thanks

While repair can be less than new, but isn't an all-new factory style exhaust around $2000 from knisely and only in the $3000 range for power flow?

Powerflow is expensive, over 4500$  and slim to no documented performance gains on fuel injected Mooney’s

And if I recall prior threads discussing its annual maintenance, there is a bit more required of it than our stock exhaust.

PF  - It has to come apart every year for lubing of the slip joints IIRC

You can visually inspect and pressure check the original muffler in place.

Believe me when I say that the original comes back from CAP as good as any new factory muffler.

The same with Dawley (only maybe more costly than CAP)
