I may have the rarest skiff..........

Heavy?

 

There is stainless and then, there is stainless. I have owned a 1988 Dodge van since new, which now has 189,000 miles on it. The original stainless muffler is still just fine and I just had the catalytic converter replaced for the first time this week.

I don't know what the muffler on our 1987 Taurus was made of, but it ate them every few years. A vehicle that is used for short trips would corrode a muffler far faster (in miles driven) than a vehicle used on long trips, like our van.

 

moisture condenses in the cooler muffler on short trips. Acids form when the water combines with residual chemicals because the cat isn't up to temp either. This doesn't help much with certain types of Stainless as it is only "Just" stainless. Long trips allow things to get to get to proper temp and condensation isn't a problem.

 

My Taurus was driven almost entirely on trips of an hour or more: long commute! The GM was bought a year before I retired so spent mot of its days on local trips. So environmentally the Ford has the best of the deal. I don't buy Fords any more. The 2 GMs I have had have been better than any of my other brands including the vaunted Toyotas: can't understand why they got into so much trouble.

Are we off the topic yet?

 

Yes...!

I was kinda hoping the OP would show us some pics of this thing! Mebe it is the shinny stuff, I have seen some odd things over the years.
