Stock exhaust - stainless or not?

[wawazat]

I'm trying to determine if the stock exhaust on my truck is stainless steel. I've searched, but all I've been able to determine is that a lot of you have custom exhaust systems on your trucks



I know that a magnet sticks to the tip, but I also know certain grades of stainless will attract a magnet.



Can anyone tell me what I've got? I want to clean/polish the exhaust tip and don't want to remove any coatings if the system is not stainless.



Thanks,

Todd

Not 100% sure, but I don't think the exhaust on the diesels is stainless. I looked at the sticker that came on my truck and no mention is made of stainless exhaust.

I am fairly sure it is stainless as are a lot of Chrysler products. It was a lot tougher to cut than exhaust pipe normally is.

Wawazat,



The down pipe is reputed to be stainless and the rest aluminized. The stainless holds temps better and lives longer so that's the probable reason Dodge went to it for the down pipe only.

A-lum-in-ized

I always assumed the only reason the auto manufacturers went to stainless (in gassers) was because of the heat from the increased emissions equipment. I also assumed that, because of the oily nature of the diesel exhaust, the exhaust systems just naturally last longer. I agree with Mark's post as to the make-up of our systems. I was going to mention "aluminized" in my previous post but couldn't come up with it or spell it if I did .
