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

5kW at the back wheels ain't bad! I gather the rest of the system was the same (my memory isn't what it could be).

Yeah the only thing that was changed was the headers.

Not bad at all...

so how long will it be before the next mod (modifcation bug will be biting hard shortly...)

Kelli,

The modification bug bit when i first got the new exhaust a few months back. It has it's teeth firmly implanted on my my butt cheeks!! Just been sorting out some performance issues with the exhaust i got originally. Now that thats all sorted i want to do a full engine rebuild, alloy heads, cam and intake to be changed. Maybe even a stroker in there somewhere depends on how long it takes me save....

Jase,

Thats a good increase, good to hear you sorted your power decrease problem as well.
Are your new headers ceramic or HPC coated??
Not a BSR part el2xr8).

Geez now i'm worried that my recent 2.5 inch mandrel exhaust upgrade will do nothing to increase power. :redhrm: :redhrm:

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.
As for the power thing, what can i say??? Dyno figures can be fudged and you guys need to be really carefull as i have learnt. I'm not going to post my findings up here simply because of the people involved. I will say though that the place i get my car dynoed (they haven't done any work on my car) are very acurate and know their stuff. They do alot of porsche cup cars and can dyno a car in perth bring it over here and be accurate to 1kw.
