I think that the Downey's come either stainless or ceramic coated. Some folk like to get stainless and them get them JetHot coated for added heat insulation. The ceramic coating has been know to chip off after a while

Who would tipically Jethot coat them? Local Speed Shops?

 

Jeff:
See my photos of ceramic JBAs fresh out of the box and installed after about 12K. Tundra is a pain to install the center exhaust bolts (raised engine and unbolted motor mounts) but otherwise a direct bolt on easy 4-5 hr, start to finish, install.

Went to JBA (in San Diego) and looked at both coated and uncoated. Coated will reduce the heat somewhat under the hood and as you can see they don't change color. Note the engine photo shown is really dusty adn dirty after running around in Mexico for a couple of weeks.

Hope this helps

I guess I'll find out how much of a pain it is, but it doesn't really look that bad to me to install. Compared to my mustang and my wifes camaro there is a ton of room. Did you work from under the truck? Those look pretty sweet though I can't tell they're coated from the pics. Is it a fairly light coating?

Is there a cheaper place to get them than Truck Performance?

 

Worked from bottom, top and front of engine. Recommend removing the motor mounts and raise engine 2-3", makes getting to the center bolts easier. If you have a set of the new 15° Craftsman ratchet wrenches it will make it easier still. Don't forget a milk crate to stand on.

You're right, definitely more room to work than my old Camero.

Yes, they are a silver color, medium gloss, ceramic coating. Pull an older nickel out of your pocket; thats pretty close to the color now. Flash made them look bright and shiny in the photo.

Got mine from this site, Lon had a deal with JBA for TS members, another way membership saves This one purchase saved me enough to keep my membership going for years to come. Check with Lon to see if TS still has a deal for members.

Let us know how you make out.

 

Center exhaust manifold bolts

I had the most trouble with the center "bolts" too. The nuts on the original manifolds were tough to get to, but I found that I could use a socket and short extension from the top side, and just go in between the manifold and the motor mount without jacking anything up. I used the original nuts to install my new headers instead of the supplied bolts. I can see where it might be pretty hard to get those bolts in. With the JBA's on, you can reach and tighten all of the nuts from the top side with a combination wrench. Getting the old ones off and the new ones on will be a good test of your patience!
