I've had a few PM's and questions regarding where I got my exhaust ceramic coated. They're mainly a Porsche site. It cost $225 for the coating and it took about 2-3 days.

I had the exhausted picked up at my house and brought to my house and installed by Daniel, who runs RSi mobile install. He charges a drive fee per mile, and then it was $100 to have the exhaust installed, which is about what a shop would charge, but it was done in my garage and I didn't have to wait around at a shop. He also sells RD-Sport stuff. He's done good work for me in the past. He also does some work at RD-Sport in Irvine when they need some help.
