Advice from dealer on 2010 T100 was that an easy break-in period on an EFI model would blue the pipes less than a carb model. Would turn more of the gold color. The other day I left the choke (basically a high idle) on too long only to find the pipes glowing red. After cooled, my new pipes are blue. Wasn't sure if I wanted or would like blue pipes, but looks like i'm gonna like em now. Only took 100 miles (and a little mistake on the choke) to get those pipes blue.
