Freshen up exhaust manifolds

[Canuck]

What is the best thing to do with my exhaust manifolds? They have never been off the car before. I want to get them freshened up and want them to look good for a long time.

Sand blast them, check for cracks, powder coat them cast, reinstall.

I had mine ceramic coated and they are almost bullet proof. Trick is doing them inside and out with the ceramic coating and it is hard to find a good coating place that will get as far inside as possible.

hey Aaron we have a old race guy that ceramic coats headers and exhaust manifolds, and anything else you like.  He is here in Oregon and I have used him on 3 different projects.  This last winter he coated a pair of LS manifolds black for $275 and they look great

There’s a shop on my town that does powder coating so I’ll check them out.

Has anyone had good results with Slip Plate or similar coatings? I want something that will last a long time.

I used a ceramic paint on my headers that I got from a guy in Carlisle. Now if I ever get them on the car I'll let you know how they hold up. But they look great now lol.

What’s the best way to deal with the tin heat riser in the manifolds? How are you guys restoring that part and reinstalling on the manifold?

Are you talking about the heat stove thing? I believe they are available for small blocks, for big blocks they cost an arm and a leg. They are held on with rivets.

Steve is right.  You can buy the small block ones aftermarket.  I bought one along with the rivits.  Once you have the manifold off it isn't real hard to remove the old rivits and the new ones just tap into the holes where the old rivits were removed.
