Not sure if magnet gives definite answer. According to this Stainless Steel - Sorting and Identification Tests magnet test can differentiate "Austenitic (300 Series) stainless steels from other steels." Do you know if magnet sticks to Lexus exhaust?
One true way to tell, is to see if an intentionally caused scratch in one area corrodes.
SS will not rust at all if scratched.
Interesting thread. I like SS and use SS hardware on all my aftermarket addons if possible right down to Fog light hardware Etc..
I did notice however SS fasteners tend to be softer than steel to some extent.
Sorry for the blab, and veering of the exhaust system topic.
In my opinion, If yu were to ask the dealer or Toyota themselves I doubt yu will get a conclusive consistent answer. If your exhaust was trully SS it generally would be documented and listed as a selling feature in the Model Brochure.
Friend of mine has 2003 Lexus RX300. I looked at his exhaust and there is some corrosion on the pipes there. Nothing major but it is definately not stainless
Yep I have been looking at buying a a used Higlander here in Northern New England and all the Highlanders I ahve seen have not had any exhuast corrosion. If not SS a VERY good coating!!
