painting downpipe and manifold
I got Hi-temp paint made for headers.. but it has to be "baked" after painting.. is it okay to put the manifold and dp in the oven.. any good/bad experences will help, thankyou

Re: painting downpipe and manifold (dwn4cause)
Seems like a really bad idea to me. Turbo headers get very hot, hotter than any paint I have ever seen can handle, we are talking like 2000 Fareheit thats sustained temp not peak. Bottom like not a good idea, if you want the manifold and dp coated for those types of temps look into ceramic coating.

Re: painting downpipe and manifold (BlackKnight7)
i used 1900 degree vht spray paint on my manifold and it has never flaked before.
why dont you paint it and then run the car hard for like 10-15 min then let it sit over night wouldnt that be the same as bakeing it in the oven. ???

Sounds like driving it after painting would be the equivelent to baking them. But I don't see why it would be a problem tp throw them in the oven.

The problem is that your oven will be useless after baking the paint on your dp. i have heard tha the paint smell gets absorbed in the oven. I would put it on then "drive it like you stole it" for a while.

if you turbo manifold gets that hot, your pistons should be melting. An average and safe exhaust gas temp is 1600 (if that), so how will the turbo manifold get hotter than the gas that makes it hot?

1. I'm sure 2000 was simply said because it is a nice conservative guess.
2. 1600 is an "average safe exhaust gas temp" which means that you can't depend on it being the peak. You are as well don't want to set something up so that it can only withstand the average temp. 2000*F is a 25% safety margin, compared to 1600*F, which really isn't that extreme.
3. We are talking sustained temperatures here, not a quick peak. Painting things like brakes is an entirely different story.

I cured my valve cover in the oven after i painted it, and omfg it smelled like paint for a week.
I had to turn the oven to its highest setting (like 550 or soemthin) and let it sit all day to burn the bejezzus outta the inside so i could freakin use it again.
Goin without oven-fresh pizza =

So 2000 was a little high, 1800 degree temps are definitely possible especially in conditions where timing is retarded. Personally I do not trust something that has a small buffer zone like that. I have heard more than enough testimonials about painted on coatings burning off.
Also I wanted to apolgize for psutohijacking the thread. Like was said earlier backing them in an oven used to cook food is a bad idea, but if you find an junk oven and use that cook the paint on that would work well. Putting the pieces on the car would work assuming that you did not have to back the parts while they were still wet...messy.
