I've been doing some research into this, and apparently European car manufacturers have started ceramic coating their exhaust manifolds on a lot of their cars. While they say that the horsepower is a bonus, the true reason behind the sudden coating is to help the car to pass the Euro 5 emission standard.
I can understand hotter exhaust temp= higher velocity gas, and the hotter temperature may help to burn unused fuel, but I'm curious to how it would feel on a street car.
red_ghost, if you would be so kind to answer my questions, what parts did you get ceramic coated? I'm starting to think that getting my exhaust manifolds done wouldn't be a bad idea.
