Anyone have a valid dyno testing comparing coated to uncoated headers without any other variables?
Is there really a performance benefit in getting coated headers as opposed to uncoated.
I am referring to longtubes here.

very little benefit ie anti rust cooler under hood temps. I don't believe it will speed up the exhaust velocity any so I would say little or no power increase but I have no real world data.

It may not be wise to coat stainless steel headers (I am not talking about 409 mild steel).
