Cleaning exhaust headers.

[Gone in 60]

There's a company here in O.C. called Burns Stainless, who makes custom stainless headers and exhaust.
They used to make a polish called "Manifold Destiny" which was awesome for stainless headers. Unfortunately they discontinued it.
I saw them at a show recently, and they said they're about to release a polish that's even better, so hoping that comes soon.
