It's probably a low grade stainless steel and in that cause it wouldn't really matter but if you want them clean, pull at your phone book and look up a bead/media blaster it will cost 40-70 bucks I assume at most then when you get
Them back paint them with Vht flameproof paint, then install, start car for 5min shut of let cool, then 10mins then shut off let cool then a 30 min drive then let cool, this will allow the paint to cure properly

I was reading on the web that I could also sandpaper them down or use a wire wheel. Should I try that before the blasting? The rust isn't super super bad..i don't think. I would post pics but at work hehe.

Ya sanding them works to or a wire wheel on a grinder, but bead blasting leaves it perfect ad the paint sticks better

And I'm positive this mid pipe is stainless steel and it might just be discoloration your seeing an not rust

Are they chrome plated or just bare steal? If they're chrome plated, it's going to be really had to sand down the chrome. It's much better to just get the chrome removed with a some chemicals and a bead blaster. Then use high-temp header paint and coat them black.

That's what I would do to have the cleanest finish!

no chrome just bare metal. since I won't be picking them up until I get off work I couldn't say if it's discoloration or not yet. He just sent a picture to me and said that they had a lil rust on them and I come come pick them up as he's getting rid of all his s197 parts since he moved over to bmw. I'll have more information later when I actually get my hands on them. I just like to think ahead on things.

It can be stainless and still rust. If its a 400 series stainless than it will rust and even pit some. Most stainless exhaust are made from this. High end systems are made from a 300 series stainless and will not rust. The easiest way to tell is a magnet will lightly stick on 400 series but not at all on 300 series
