Default Anyone have a little rust on there stainless headers?

I know 304 Stainless isn't supposed to rust (thats why I bought them and paid so much) but I found a little spotted rust on some of the primaries and a little more on the welds. I've only had them installed on my car since the beginnig of March ~2.5 months. My pops was telling me that stainless isn't 100 pure so was thinking that its the impurities rusting. Any thoughts? I'm kinda pissed.

My headers are doing the same thing. Not much but enough to be annoying

True....very annoying. What ones do you have? I don't want these every rust through. That's why I bought them. If it is just a little bit on the surface and never get any worse then I can deal with that.

it depends on what grade of steel is used.
some minor surface rust is normal with stainless.

I hope not I just bought Kooks SS headers so they would not rust. But I guess some will always be there. My SS catback is rusting.

Kooks and QTP use 304 which is thicker and a better grade than 409, which I believe SLP uses.

The rust could be coming off the flanges because they are not stainless.
