This is picking up from another current thread where Ulix said the old SERRA headers were not good for the street. The headers on my Bertone looked to be essentially the same as shown here:
Hard to see but the collector is just below and to the rear of the frame member. Ulix is this a "bad" configuration for the street which causes a flat spot around 2,000 to 3,000 rpm? As I had noted in the other exhaust thread my DCOEs ran very rich off idle but jetted OK at idle and higher rpm and I could not find any jetting that would lean out the "flat spot".
