Protecting exhaust from rust

[igor]

I bought myself a jap catback (polished mild steel). I always thought stainless steel exhaust were a bit of a wank, but I now am having second thoughts about it rusting.

Would it make sense to spray the flange joints with some high temperature paint? Any other tips to prevent mild steel units from rusting?

Try the high temp 1500+ VHT Exhaust Manifold and Header Paint.

If this doesn't work nothing will.

On saying that all the paint, i've seen used on exhaust systems usually flakes and comes off eventually. Especially on turbo charged vehicle exhaust systems.
