it is due to reduced kerb weight of the car

A car that runs on fuel cells only has a similar overall efficiency to a car that runs on petrol because a car that runs on fuel cells is designed to not pollute the Earth but you need renewable energy resources to generate the electricity which is like the efficiency of the petrol pollution. That was what I put on my homework anywayz. :)
High performance exhausts can have a small, yet statistically insignificant, impact on fuel efficiency. They tend to be installed for a differenct exhaust sound or improved power, not improved fuel mileage.
