hi all, i was cleaning the rap the other day & noticed a bolt, one in each of the header pipes (front & rear) does anyone know what purpose these serve, are these some sort of restriction in the header pipes ???
Sorry mate, no cheap tuning opertunity
If you remove these you can put a lambda (co) sensor in there
This is sometimes used in a workshop for setting up the correct fuel/air mixture
So way you can see each cilinder separate co output.
