I have the Megan exhaust. I had mine ceramic coated at a place called Powder 1 in San Diego. They did a pretty good job. I think they charged me around 200 but would have to double check.
The ceramic coating is pretty much a matte black. I like the look. It certainly isn't gloss black though. However it really completed the look for me as I have black wheels and black everything else on my MR coupe.
I need to wash my car. When I do I will post up a couple pics.
