Pete, had it dynoed yesterday. The red is with old headers from herrods and the blue is with the HM headers. Definate improvment!!!

so how long will it be before the next mod (modifcation bug will be biting hard shortly...)
I'm not sure, i don't think they are but it doesn't really need it anyway. They are stainless though, with something over it i think it's just paint though but it hasn't discoloured or anything so don't know.EF_Falcon_GuY said:Jase,
Thats a good increase, good to hear you sorted your power decrease problem as well.
Are your new headers ceramic or HPC coated??
