I got a 99 Zl 600 carb with a clutch kit and some suspension upgrades. This year I'm putting on a tempa flow to help with the performamce as well as the mileage. As I looked at my pipe I thought maybe I'll just get it ceramic coated (looks good & you don't have to paint it every year). My question is with just the ceramic coating does it make the engine run richer, leaner or about the same? What do you guys think? Any first hand experience out there?
