When I had my Cobra Roadster, I never noticed any exhaust fumes at all at any speed. I did notice the noise and wore ear plugs when going very far. Could you have an exhaust leak in the headers or up front that is letting some fumes come back into the car? Mine ran on the rich side until it was warmed up as it had a racing set up and no choke on the carb.
