I had my done by a Engineered Applied Appications, Phone# 323-585-2894 in Vernon, CA and they looked like polished aluminum, cool...Had a very good service and no problem what so ever, maybe I was just lucky...They do a lot of coating for race cars too...I was recommended by people who built Shelly Cobras Race cars in Torrance, right next to the airport...No problems with size or anything at all, that's my 2 cents

I had the same experience as Colyn when I had my pipes coated on my ES.  I sent my exhaust to Jet Hot (which is primarily for cars) and when I got it back, some joints were a little loose but others wouldn't fit at all.  I don't know how they did it, but some of the joints were visibly out of round.  I had to take them to another shop to try to get them bent back into shape, which resulted in slightly leaky joints.  Eventually, I had to have a new exhaust made.  I took the new pipes to Olympic Coatings in Escondido and had their gray high temp coating put on.  Several years and a few hundred hours later, it's still going strong.  I had both the inside and outside of the pipes done, however it's important to remember NOT to coat the pipe running through the heat muff.  Doing so will greatly reduce the heat transfer.
