Jet hot coating is probably your best route. That's how I did mine. Dry exhaust xr1 drag with mufflers. Think I paid around 200$. They came out great, nice and chiny
I've sprayed a bunch of different headers with the VHT stuff... even the "ceramic" look ended up really nice and last for a long time, everyone asked me where I got the headers coated I just scotchbrited the headers and cleaned them well
