Pretty sure you're thinking of 409ss which is right above mild steel. 304 can surface rust but that's because things stick to it and rust. It'd take 1000 years to break all the way through. And here's what I mean, 304ss exhaust with surface rust from who knows what sticking to it...
A light polish gets everything off the steel and brings the shine back out. Again it'd take 1000 years and 1000 polishes to get through 16 gauge 304.
And race cars don't drive on the street or use a 370z. The under hood temps of these cars suck along with their oil cooling system. Running an unwrapped header in THIS car is just plan retarded! |
The exhaust that rotted was 304 dude. It wasn't a huge hole, but it was big enough to leak. It was an Invidia catless bellmouth downpipe made from 304 stainless steel. 304 definitely doesn't have a super high chromium percentage does it? The exhaust gas temps at the downpipe of a modified STi get pretty damn hot. With constant heating and cooling, tough weather and 2 years it happened. Not making it up... May have a picture somewhere.
