What he said ^^^^

If you're thinking of painting them, I'd do what he said as best you can first, or the paint will start to flake off in a few days.

After you get the most off you can, get a rust-converter product. Then paint. Rust converter change the oxides into a different chemical compound, so it can't rust out from underneath the paint again.

just make sure you dont take off too much stuff and put a hole in the manifolds, your car will sound like crap. It makes a ticking noise when you hit the gas

If it'* that bad, don't bother cleaning the rust. You should have replaced them years ago
