After looking through the archives, I can't find any threads regarding the use of ceramic headers and fueling. My question is, if you have ceramic headers, does it change your fuel/air ratio? I am considering the upgrade from American Sport Bike and am hoping for some feedback first. | ||

Should only change the amount of heat you feel. I cant think of a reason it would affect fueling | ||

The ceramic coat will cut back the radiant heat by a large margin. It will actually give a tiny performance gain since the exhaust gas temperature stays up, the less dense hot gas will flow better. On my dragbikes I had the pipes coated internally as well...the pipe would be cool enough to touch within minutes of making a pass. Add in the thing about the coating being practically impervious...If I ever have reason to pull the exhaust system off my XB, it will get the treatment. | ||

I've noticed a gain of about 1mpg since I got the headers wrapped on mine. I do the same riding day in, day out (commuting across a city), so my fuel economy is typically rock solid, and it went from 41mpg to 42mpg after the headers were wrapped. It *might* lean the mixture out a tiny bit, due to improved flow/scavenging, but I don't know that it would be enough to worry about. Easy way to tell would be to get an AFR log before and after on a dyno. | ||

My pipes are ceramic coated, no issues at all with fueling. | ||

Mine is an 08, had jet hot coat them, reduce temps at legs and don't notice pegs as hot. I'm sure my tune is a big help. I also moved the 02 sensors into the collectors very close to where the 09 are. That seems to be the biggest gain. There not in the hottest spot on the pipe, front and rear. If you do go that way, when you rotate the motor down, that's the time to put the heat blanket in and line the inside of the frame. For me, no more hot boiling fuel and stinky garage after ridding. Cooler fuel more power. It all adds up, worth the effort? seems to have helped. Scott |
