Where are you buying ebay/ssa s13 dual <200$ cat-backs now a days?

The HKS is 409 stainless, which isn't as corrosion resistant than 304 but way way better than aluminized mild steel. 409 stainless will get a surface tarnish if exposed to salt, but will hold up to winters. A s13 will rot in the rust belt before the HKS will.

Check out amazon for cheapo exhausts too. I snagged a $200 CAD 304 stainless catback a few years back before going to the HKS.

well, that's what's a bit fuzzy. Some sites say tip, some say muffler, some say muffler different than piping, some even say mild for piping. I looked a few used "sport" ones and rust was fairly noticeable. I might regret it since I'm a bit slammed and these ebay ones hang a bit low compared to single HKS.

HKS themselves say it's 409.

Just checked mine; tip and muffler body is 304, rest is 409.

I couldn't find it on their website. You got a link? I think I posted here some spec sheet that said S3 (which I think is basically 409), but unlike other models, they did not differentiate between piping and muffler body.

It's good to have a decent option if this other one ends up scrapped.

I don't know why anyone in their right mind would drive an S-chassis in a season where 409 SS rusting is a concern, in this day and age.
