The paint has held up very well on the intake pipes, but it is flaking noticeably on the lower downpipe section. I'd imagine that on a manifold or upper downpipe section it would not work at all.

On the other hand, the ceramic coating on the upper downpipe section is still looking good. I had it done in an aluminum finish and while it's taken on a bit of a patina, it's not chipping or flaking at all. Even the inside is still beautiful.
My downpipe has held up really well with the Duplicolor High Heat Ceramic paint. Actually the flaking is more present on the lower section where it's subjected to road debris / salt etc.

I think they would last a good while at least until you decided to do a real setup.

High temp paint(1500 degrees) will work well on intercooler piping and the lower section of your dowpipe. Just make sure to clean any oil or grease on these pipes before painting them. Lighting scuffing your piping with 200 grit sandpaper will also help the paint adhesion.

Painting your downpipe and manifold is a waste of time. It will flake off in a matter of minutes. Ask me how I know. I heard BBQ paint works, but do not know from personal experience. I suggest going straight to ceramic coating if you're worried about coating your manifold and downpipe.

As for your search for straight aluminized piping, I bought my 10ft 2.5 exhaust section at a local napa store for 29.99.

Maybe in a few months I'll go back and redo it with some nice mandrel 6061 AL, and the exhaust in 304 SS... right now I just want boost and crushed bends will work just fine, especially if they're only slight bends. I'll probably order a few U-bends to cut up for the sharp bends
