does a broken back box affect fuel economy?

  1. #1
    the other day my back box finally rusted through and isnt actually attached to the center pipe any more, bit random but does it affect fuel consumption because i have gone trough 20 quid in 3 days, the same time my back box broke.

    Yes it will because the engine isn`t getting rid of exhaust gases properly.
