It's 409 stainless- a low grade. Only one step up from mild steel. It's also aluminized. I thought I'd try POR 20 high temp paint ("black velvet"), but I'm open to suggestions. POR 20 also recommends a "sweep" of sand blasting on stainless.

QUOTE(BigDBass @ Jun 2 2010, 11:04 PM)  How 'bout ceramic coating it? I'd do that if I could find a place locally. Drop off/pick up kind of thing. I don't want the car down too long. I guess I could coat it after the season (thinking out loud). Any recommendations of a good shop? |

Making some progress. I sawed off the tailpipe, just upstream from the tack weld, cut it shorter (where it goes into the muffler), and shoved it in further. This aligned it with the notch in the valance. (per Azbill's earlier suggestion). Took it in for the final weld, including attaching the bung for the O2 sensor.
I'm holding off on painting it. I'm thinking that at the end of the season, I'll have it blasted and maybe go the jet-hot coating route. I'll have to ship it somewhere to be done (no outlets around here), but at the end of the season, that'll work. Note how the original reinforcement brace from the inlet flange mates to the new muffler. Also note the original Bursch tailpipe. Installed pics below. A few more in the follow on post. Jim   |

Honestly I would just give it some rattlecan high temp black paint. I painted RIGHT over my polished stainless steel magnaflow muffler. One month and its still good on my honda CRX. Only prep work was a 30 seconds scuff up.
If you have to respray it every year, so what? |
