Exhaust Pipe Rust or Dirt?
Watch this C7 video. Then notice that the exhaust pipes look like they might have rust in them.

Is it rust or dirt? Rust seems kind of odd for such a young car, but I suppose anything is possible.
PS: I'm still getting one of the first ones out. (#94 on GMer's list.)

I can't open that vid on my phone, but I think I've seen what you're talking about. It looked like heat discoloration to me, and it seemed more pronounced on the two outside valved pipes. That's my guess.

If you are talking about the exhaust tips, they are polished stainless steel - no rust. But you will get combustion by-products build-up on them. It can be cleaned off.

And I do hope it can be cleaned off.

The factory polish of the tips is not that great. Here is the solution.

I use this kit on my C6 NPP and it makes the tips shine like a mirror. If you don't want to buy this kit you can get the materials at any metal polishing supply, the kit is nice because they provide the right size buffing pads and all the compounds you need in one package.

That is what I thought you were talking about. The tips are polished stainless steel. Stainless steel generally will not "rust". The tips can definitely be cleaned. In fact, frequent cleaning is one of the best ways to prevent stainless steel corrosion. Do not use abrasives.

1) Does it use anything abrasive?
2) Got any pictures you can post?

I though soot was black, or grey/black but not redish. So this looks more like rust, but I'm hoping I'm wrong. And I understand rust can't take hold on chrome, but that just raises the question as to what it really is.

Stainless steel, not chrome. Some stainless steel can rust.

I was using Simichrome back in the 80's on my BMW R100RT bike. It's just one of those things every detail person should own. Worked like magic on the chrome and really good for removing the light scratches on the plexiglass windshield. Worked on all polished metal surfaces such as alloy's too. Rub it on, then rub it off.

It is not a matter of cheapness, it is a matter of the alloy. 300 series does not rust, 400 series does get surface rust. 400 is stronger so it has its uses.
