Factory Exhaust Material

[dstanky]

I have a 22 Mustang GT with active exhaust. I was wondering if anyone knows if it's Stainless and which grade. I thought it was 409. However, I can't find the specs anywhere.

Not certain but probably 409. It turns dark brown and does rust

409 sounds right. Can’t imagine they use aluminized steel considering all the different climates they sell in.
