20100170235 | Vannoy funnel exhaust system - The passive energy saving device, disclosed herein, may be integrated directly into or added to the exhaust system of an internal combustion engine, to increase the system's fuel efficiency, by acting to reduce the overall backpressure of the total engine and exhaust system.
