Thanks Rich. Yep, mine went from brown to black to flaking off. On both sides
this occurred in the same place... Not on the ram horns but down lower near the
collector. Even though this started happening shortly after I put them on, I'm
sure I'm out of warranty as I bought/installed them back in Sept. '98.

Tom,
The way mine went bad is this. Supposedly the shiney new silver appearance
is supposed to turn to a satin low-luster when it fully breaks in. This
happened as I was told it would. Several months after this, the coating
started turning brown. Sort of like a rust color. What I have just found
out is this. The silver coating is rated up to around 1200-1300 degrees.
Apparently, the magnum engines product temperatures in excess of this rating
causing the coating to breakdown.
I stated earlier they were re-coating them under warranty with an upgraded
coating. I may be in slight error here. There might be a small charge to
cover the cost of upgrading to the more resilent coating material. This
black coating is supposed to handle temperatures up to 2000 degrees. It is
slightly more expensive. Even so, I'm tired of pulling the headers off to
have them re-coated. A small fee would still be worth it to me.
Rich
