Cheap stainless eBay headers?

I have a set of stainless eBay shorty headers on my ram. They fit great, don't leak, and haven't rusted a bit in 5+ years. They are a dull goldish-brown now though due to heat discoloration over the years.

Also have had 2 sets of the "eBay special" stainless long tube headers on 2 different BMWs. They also fit great like my truck headers and have worked perfectly for years on my daily driven 97 M3. That car gets driven HARD through the rain, snow, and shine.
