So, I still have pipe laying around from changing my exhaust out. I cleaned some of the old pipe with a wire wheel, hmm, this sure doesnt look like stainless... grab a magnet, not staiinless in the least bit. Had my car up, checked headers, nope, checked immediately after flex pipe, nope. The only thing I couldnt check was the muffler. So to all those who say the exhaust on the 09+ is stainless, hate to say, but its not. And the article that says it is is for GM canada​. Im not sure if they changed the exhaust for canadian cars or something, but my 2010 sure as **** isnt stainless
